I have the stock Can Am screen and I think it does a pretty good job. But it does look a little silly.

It has that weird key and I often forget to even take it out. I'll be walking around Walmart and suddenly think "Oh crap I left the key in it. Do I want to walk out to the lot or just assume most bad guys don't even know that's a key?"

On one of the demos on Youtube a guy said right pegs are difficult because the weight of the master cylinder binds. He reached under and pushed up on the master cylinder and it slid around fine. I only adjusted mine once (just got it yesterday) but lifting up on the master I didn't have a problem.

Comfort is relative. I row pretty often, siting on 1/4" of foam on a hard wood plank, so I find my stock Ryker seat is very comfortable. My suggestion would be that you sit on a bucket for an hour before you tgo riding. Your Ryker seat will feel like heaven.
