Flip a coin, buy one set, wear em out and then try the other set. I went with PR2s after a set of the now older stradas (which I loved BTW), it was a backward feeling, the Angels came out, JW had a sale and I tried them out, still love em, they have a coupla thou left in em but I have the 55s ready to go. What I like may suck for someone else so experiment, all three being discussed are better then the OEM stones.
