I dont know what kind of riding you do, but I had t-5's, t-6's, cpi's and LRD's. Nothing ran as good and as rider friendly as my LRD's. I built my engine to drag race and the LRD's arent cutting it. I would like to try a set of the SST's on my other bike though. My buddy had a set and said they pulled pretty good on the top. I dont know if you're interested in trades, but I do got a damn nice set of LRD's I'd trade. Hell, I might even throw in some cash. Lemme know. PM me, thats the fastest way to get ahold of me. The LRD's are fully adjustable so you can adjust them for top end or bottom end. Nastyracing is a huge LRD guy and if you have questions and need another opinion ask him as well.
