had Fatties, had T5s, had PT Mids, had PT Highs, had Pro Circuits. but, never had a CPI, Shearer type of pipe. I don't care so much about overall power, but what's more important to me is smoothness. I'd love a set of CPIs, even if they lacked in the low end, but built power smoothly into the never-ending top end. What I mean by smoothness is if I take it out to dune in the trails or something and its super peaky and hard to keep in any power, but if they're smooth, even low power in the bottom end, if it builds smoothly, then it'll still be better at duning in the trails and such.
in my experience, the T5s were much 'peakier' than the Fatties and PT Highs and weren't as fun for me to ride, similar type of power, delivery albeit a lot more, as the stockers, peaky with a hard hit. I'm not a fan of 'hit', i prefer progression. Again, in my experience, I've never ridden anything that built power as smooth as the PT pipes, both Highs and Mids... just incredibly smooth.
I'm fairly sure I'm going to get another set of PT Highs, unless I decide to try some CPIs but don't think so, I like to wear shorts sometimes when I'm cruising, testing and stuff.
