Driving impressions please, comparisons

Well today I was at the Run-What-Ya Brung drags at Capac,MI and watched a guy make two runs with a xc 700htg piped sled with clutched secondary. He then pulled it off and installed a Team perf. Rapid reaction out of the box. He pulled the skis 20 ft further and the track started ratchting ou tof the hole. He was quite impressed. And he hadn't installed the primary spring that they sent yet. I'd buy one for sure.
