I bought a set of Woodcraft's from Blair for my street bike, can't comment on crashability but they appear to be quality pieces and replaceable tubes are nice.
Anything Woodcraft isn't really cheap by any standard though, Vortex might be cheaper and better bang for the buck?
If you want to be fast get some woodcrafts from Blair,
But seriously woodcraft and attack are the only company the make a split clamp design meaning you can take the entire clip on off without sliding out your fork
Get woodcraft Matt. The bars are longer and the angle is adjustable which allows you to customize the angle for what is most comfortable for you and the extra length gives more leverge to make turning easier on you.
Also spare bars are all of 20 bucks and all the bars fit in all the clipons so it does not matter what brand you have someone will likey have a spare bar if you are out.
an bent or busted bar is a crappy thing to keep you out of the next race if everything else is good to go.
