I LOVE clipless! I have been riding them for about 10 years now. They are fantastic - don't know what i would do without 'em. You get used to them quick and then you can alwasy unclick in a second. The only time I won't use them is when I am practicing wheelies (don't wanna fall of the back of the bike

otherwise I use them everwhere> I have even endo'd with clipless pedals and been fine clicking out and getting over the handlebars on my feet.
I have Onza's by the way which are pretty much ancient. I herad the Crank bros. ones are real easy in - out
IT takes a month or so to really get used to it. I just like feeling attached to the bike, I can really throw it around. Plus I can hop over stuff much easier.
