I like to try to go as big as I can, that being said, a higher bb bike is better for me.
However, I do not (and I think noone else does) rides with the idea in mind of attracting someone to the sport.
We all ride to have our own fun, being big gaps and sidehops or manual-ing all over the parks.
Each one of us does what us personally consider as fun.
I know that old videos (really old not 2007) look really fun in what they do and the whole vibe of the video is pretty cool, but that doesn't mean I want to imitate it, like watching a bmx video, I think it's cool but it's not something I really want to do (not saying I never will either).
IF someone looks at what WE do and thinks it looks amazing then great, it'd be amazing to get that person into the sport; but getting that person into the sport isn't really any rider's main goal.
