nice elraido! same setup we used, just a different material. If i had to guess stanchy, the road fabric would hold up to 350+ fps no problem since the vinyl we were using held up fine to hot shots.
We actually got tired of wasting paint trying to break it. We even had an x7 phenom set hot with burst/full auto I forget which and it wasn't an issue. its not stretched super tight so it bounces alot of shots unless you have hyper fragile tournament paint. Overall, it would take some real effort to put a hole in it.
