Why ?
360 degrees divided by 3 equals 120 degrees.....even.
Having one fire every 120 degrees should make for smooth, balanced operation.
And guess what......it DOES !!

Any engine with an manual transmission can be "lugged" to the point of damage.
Your "especially" is true but without adding that qualifier, your other statement and claim that it is not possible to damage "modern engine" by lugging is just simply not true.

The 1330 does have a lot of low end torque.
Another .02 for the pile. 
my answer was similar to yours except the downshifting method. I always downshift before the machine does it because if i wait for that it waits far too long and does not rev match at all correctly. The result is a terrible inertia effect and the worst downshifts ever. Yours downshifts smoothly on its own?

The sales brochure shows the high torque in every gear from 2500 RPM to 6000 so your choice, your ryde. There is no wrong answer. The advantage you have on your F3 is that you can be pulling 94 lbft at 4500 in fifth while the RT is still on the first plateau at 4000 RPM in fifth gear at the same speed, (unless your wife drops a gear, heehee!) 
She is learning to run a gear lower than me because of that, especially in the mountains!

We too seem to run in the same gear most of the time..
The fact that the RT can usually run smoothly with the F3 in the same gear attests to the 1330 ACE being able to pull well even though it's running at 12% or so less RPM. But all the wife needs to do to get me scrambling is to slow her F3 down on a long grade to 45-50 mph, and then roll on the throttle and watch me and the RT fade in the distance.
I think she learned that trick when I was riding her 11 RT hand-me-down..
I'm just pleased that she gets the same gas mileage I do even with higher revs down the interstate. I guess pushing less wind and less weight does make a difference.

The wife has been running her RT in ECO mode to try to equal my mileage on the F3, but she still has to start station hunting before me.....

When someone is asking for advice and you give "your opinion" it might be helpful to state that that's all it is... Your Opinion!
From the "Do's and Do Nots for New Spyder Owners (can be found in the General Discussion threads)
SHIFTING SUGGESTIONS:
(The shifting-point suggestions for the 1330 and 900 series engines are explained separately.)
Shifting the 1330 models:
The “ECO” mode shift coach suggests shifting at the following rpm’s:
1st to 2nd: 1,800 rpm’s
2nd to 3rd: 1,950 rpm’s
3rd and up: 2,200 rpm’s
When manually shifting the 1330, it seems too many are over thinking it. If you are not using the ECO-mode, then just shift at around 2500-3000 rpm’s. That shift-point falls right at the beginning of the first-level power band, which is perfect. (Funny how that seems to work! See below.)
1330 Engine Power Band (Dyno-Chart Data):
1st level power band begins at approximately 2,500 — 2,700 rpm’s and remains flat until 4,000 rpm’s.
2nd level power band begins at approximately 4,500 — 4,700 rpm’s and peaks at 5,000 rpm’s.
After 5,000 rpm’s the power declines slightly until reaching 6,000 rpm’s; where the power rapidly declines; thus proving any increase in rpm’s above 6,000 rpm’s on the 1300 is inefficient and fruitless with regard to obtaining additional power and torque.
What does this mean?
It means shifting below 2,500 rpm’s can put an extra load on the machine when accelerating above a relaxed pace. While it may appear the engine has plenty of power below 2,500, it, in fact, is not producing peak performance power at that point, thus, shifting below the power band makes the engine work a bit harder. While the manual suggests shifting below 2,500 rpm’s, it is doing so with the thought the operator is accelerating at a very relaxed pace.
Some have a misperception with regard to shifting a machine within its peak power band. It is often perceived to require harder/faster acceleration; when, in fact, that is not the case.
It simply means you hold the machine in a gear longer before shifting. One does not have to takeoff from a dead stop like a drag racer to shift within a vehicle’s power band. Again, you simply hold it in each gear for a bit longer until the rpm’s reach the power band.
American’s have long been known to have a preference to low-torque machines. With that often comes the tendency to want to shift to a vehicle’s highest gear as soon as possible, and leave it there… at least until the engine begins to shake and shudder. Not a good idea with any vehicle.
Why is this important?
Over a short period of time and mileage, there would probably be little noticeable affect or damage to a machine operated below its power band under normal, relaxed conditions; however, over a longer-term, there certainly can be a excessive wear along the machine’s drivetrain.
In addition to seeking peak vehicle performance, expert/professional drivers & riders always operate their machines within its power band at all times for added control and handling. Consider it a safety precaution.
Any vehicle operated outside of its peak performance band is operated with some loss of control and efficiency — varying, of course, to the degree it is operated out of its power band.
For most owners of the 1330 engine, its lower torque seems to satisfy the inherent American “need” for an engine operating at a lower rpm.
NOTE: There is NOT a “Trailer Mode” for the 1300 model.
1330 "ECO" Shifting:(Check your manual) (Provided by PMK)
The ECO (fuel economy mode) setting reduces fuel consumption by limiting throttle response and maximum throttle opening to maintain an optimal cruising setting.
Activating the ECO Mode:
Press the "MODE" button for 2-seconds while in the Main Screen.
When activated, a green arrow will alternate with the gearbox position indicator to indicate the optimal timing to up-shift the transmission.
NOTE: The Gearbox indicator will return when the transmission is shifted.
De-Activating the ECO Mode:
Press the "MODE" button for 2-seconds while in the Main Screen.
ADDITIONAL INFORMATION: (provided by Lamonster) The throttle map changes to a more progressive acceleration; rather than a linear one. During hard acceleration there will not be an indication to shift -- the ECM understands you are accelerating and will not recommend a shift at this time. Only when the vehicle speed and acceleration have stabilized for a certain time and the ECM judges there is enough engine torque available in the next gear to keep the same speed and acceleration will an upshift indication be displayed.
Hope this helps... Rick

One problem: You actually can't use those shift-points unless the ECO Mode is engaged.

F3T gets slightly better gas mileage than my RT... both SE6
"The wife has been running her RT in ECO mode to try to equal my mileage on the F3, but she still has to start station hunting before me."
Our experience as well!! Even though the F3 is turning 12% more revolutions every mile I guess its pulling easier with less wind resistance.
