I never liked the slop the shocks had. They moved inside the body, I tried a set of RC shocks pistons and VRP's neither got rid of it. The main problem was the bushings not being tight enough, the same reason TLR went to machined internals and pistons. Our tracks have quite a few big jumps and I bent a couple front shafts on the HB stock shocks. For me I think the TLR's will last longer.
