Before bumping up to 22's I was riding a custom standard 250L with a 22" top tube and prior to that a DK R/T with a 22"tt as well. While they were the best feeling 20's I'd ever ridden, I'm really just too damn tall for a 20". I've ridden various peoples 24's and 26's over the years that showed up to the trails, but in my opinion none of them felt right and I could never go as high on them as on my 20". Granted I was riding other peoples bikes set up for them with a tt length certainly too short for me. My feet hit on xups on all big wheeled bikes and thats a major disadvantage, which would be solved with a longer tt. Also, the sunday I rode did have smaller bars than what I'm used to. I bet if it had a set of 9"s on it, I wouldn't have felt so hunched over from the high bb. The wave c was certainly one of the better 24's I've taken laps on, but in comparison to the feel of a traditional BMX bike, I think 22's are the way to go.
