Yep, I'm also throwing my Rocs up to 330' on a course, even in wooded tunnels, and I'm using DX Rocs. When I hit an early tree, I just bend it back and it doesn't fly all that much different. Frankly my bigger problem is that my Rocs don't wear fast enough, as due to some losses I'm down to just one last well worn Roc, and have to resort to Comets in place of worn Rocs. Although I have to say I liked the older stiffer DX better than this new half-R-pro DX mix they're putting out now. KC Pro Rocs are just too hard and slick for my tastes, and not that much more durable.
MVP Vectors are pretty good fit to the more durable Roc slot, I did throw them for a while. But again, a bit too slick for my tastes. I just love the grip of DX.
