Well, my track pads are a little under 1/4" ABS plastic. The aluminum rivets have failed before any of the track pads have broken. The tank is over 100lbs. and been through some pretty rough stuff. I definitely trust PVC to take paintball shots. The 4" PVC drain tube under my driveway survived a 10,000lb. Bobcat running over it all winter. The pipe would crack if the Bobcat ran over the edge of it however. Gray is the cheapest color so that's what I'll go with.... :)
