Lots of people love them, but I bent a Project Two in a short time on a commuter bike, so I'm avoiding that one, even though they look great.
Slackening the head tube angle a degree might be ok - winter bike in snow and slush and stuff.
And plastic, I mean, carbon, I don't know - I'm probably being stodgy, and I've never ridden a carbon fork, and I even have a carbon post, but I'm constantly suspicious of it. 225 lbs plus clothes and gear... on the other hand, I break metal parts plenty easy.
And the nashbar fork I was going to buy with the last coupon I had, but they spec the weight at 1300 grams - that seems insane, I have a Kona dirtjumping rigid fork that's insanely burly, and heavy, and it seems to be in the same weight ballpark.
I didn't care about weight until this bike - my first light one (<20 lbs) so I'm getting a bit weenie.
