Well.......the spyder is in getting a new clutch.
I bought my 2011 RT used in August with 18,000 miles.
Now at 25,000 miles the clutch is slipping quite noticeably and all that's left to do now is pay the dealer lots of money ($1300.00)
The dealer has all the necessary parts in stock and is hoping to have it done today so knowing how life goes I should get it back tomorrow. At least they gave me a nice loaner (2016 RTL) so I've had a chance to compare the new with the old.

When I first got the spyder I actually noticed what I call a surging at 50mph and up.
In hindsight I'm guessing that this was the beginning of the clutch wear.

As much as I tried to keep up the revs when shifting and trying not to lug the engine when cruising, I suspect I'm guilty of not doing what I knew I should do.

When I get the spyder back I'm going to try riding in trailer towing mode which will force the revs to stay higher.

So in closing all I can say is......Keep the revs up folks because it's true what they say about wearing out the clutch prematurely.
