I run a centri and love it and will always do so. They are beastly with rpms above 4000 and insane at 5000-6500. I will never go PD, YMMV
I recommend a PD for a street driven ride because it is instant gratification when using the right foot. The centri is pretty much useless below 3000-3500. It just depends on you goals, and based on what you typed, i think a Whipple will make you very happy
