If i could change mine it would be to 33mm pwk's.
I am running 34 pj's on a drag port with a cool head , v-force 3's, +4 timing and some cpi's.
34's will bog first 1/4 throttle unless you dial them in just right.
I am running them with CEL needles on the 4rth clip down and 172 mains and the bitch is ripping through the whole throttle.
