i loved my classic valve with the ult...I was dumb enouph to trade it in for in Xvalve...I should have kept it, i could walk it, plus when i was ripping on it i could out shot my revy with xboard easy. i miss it. oh well the Xvalve is nice, but i will alway miss that classic valve. when you set it up right in a clasic its awsome. i even had guys at my local paintball shop and field drooling over it =P
