The only "down side" I could find after riding one for a couple years is you loose some side to side leverage to balance your self. I was using the gunwall and my legs to pull it back up when your tipping a littke to far to one side. But you get used to it and learn to put more weight on the heal instead of the balls of your feet. Or have strong ankles! With proper foot strap location I see no downside. It really is a fun, different kind of ride. Plenty on here rode mine maybe they will chime in. But a quick test ride and really getting used to it are different things. If I had rode one for just a minute i prob wouldn't have done it. Having the straps and pole setup for you makes all the difference. I say bite the bullet and go for it. I bet You won't hate it and if you can glass it wouldn't be to much trouble to shape your own gunwalls back on later.
