'08 STP Pro (Aus version) came with Pikes, pretty set to use for 4X or DH HT. I'd be looking at a Norco Shore HT or 2nd hand Banshee Morphine, Transition Vagrant, maybe the NS Bitch / Surge
i used a gary fisher opie for about a year and a half of downhilling. thats on tracks like fort bill, glencoe and dunkeld. its a great frame but you would have to build it up custom. comes stock with shit parts. if you went down the road of a custon build you should consider it, i got my frame for £50 with cranks and seatpost
