Orange 22* series have always been a light fast frame desgined for racing. I have heard from heaps of people not to 'huck' them. However from my personal experience with them (quite a few of them in the local race scene here) I have never seen one crack and have only heard of one cracking in Adelaide. He got it professionaally welded. Then again this guy who did break his was by no menas smooth. He has blown many shcoks, cracked the uppers on 2 paris of Dorado's, the crown on a Boxxer and the arc of a Boxxer.
Also all these Oranges are getting thrashed pretty hard, in my opinion racing actually puts a frame under greater pressures than freeridng. Also these racers are hucking them with no worries, you should be fine.
Oh and by no means is the VP-Free an incapable bike for downhilling.
