I wouldn't,looks FUN! But then,it reminds me of my local trails from where we just moved from (not here),so I was used to riding rocks\etc looking lots like that (and I been riding 30 years,not counting motocross back when too,LOL!). And I rode trails like that rigid fork'd for years. That doesn't say that I'm an expert or even a great rider by any means,but you learn to pick the best,smoothest line through it (like previously said).

That said,having a suspension fork isn't only for control and speed,it is as well for comfort...my example,as some old spinal injuries progressed (meaning,bothered me more as I got older) over the last few years,I feared I was going ot have to give up mtn biking. It'd been a few years since owning a sus. fork (back when Fox RLC125's were new,what,'02,'03?),but I bought one as a last ditch effort,and viola! I can ride rough trails again.

The key is (like mentioned),don't let suspension make you lazy or dependant on it,but it can make you faster with better control once used to it.
