Yeah, I find the most difficult part is the weight. It's a Hi-ten frame and it can get a little heavy trying to whip it around.
I'm totally used to the wheel size now, so that's no difference. I think the biggest challenge is learning all the new stuff. I'll never be no Yanmar, but it's about getting on your bike and riding. The results will come from the effort.
I've only been riding for about 3 months, so I find learning trick(s) is modular or sequential process. It's really hard to bullsh*t a trick [or a link] without actually having some of the basic fundamentals mastered.
I guess right now I'm going through the process of trying to pull Karl Kruisers and 1 handed steamrollers before I can get totally crazy. I'll say that finding a "rolling groove" (a point where the bike seems to float while rolling) is close to the 2nd decent on a rollercoaster--where you've accustomed yourself to the 1st decent and now it's total enjoyment.
Why do I ride? I think it's like I'm trying to get a headstart waiting to see what happens to BMX after 2008 in Beijing, China. I believe in 2009 flatland could change it's course and become something of an "opened gift." I guess the future just depends on how today's riders accept their roles and where they want to take it. I heard there are 8000 flatlanders in the world today. So, it's become like a family. I've been away for awhile, so I'm waiting to see the direction of the sport dynamics--some good and some bad.
