Hey Everyone !!

I'm 5' 51/2" , 30 inseam. 2019 F3L with Cannonball seat.
Doing the tape measure from the gas tank up, my eyeline is approx 191/2"
Anyone run the F4 21" windshield on their F3 ?
Whats your review of it ??
Does the wind go up and over your head or hit your forehead ??
Can you see over the top of it ??
Would you have gone with the 23" instead ??

Thanks,
Tommy J.
