Has anyone here ridden the Puddle Jumper HP Round (or even just the HP) and can say how much upper range you get out of 'em vs the regular PJ? I've had two PJ's (a 5'7" and currently a 5'2") and have liked them enough that I'm considering the PJ HP RND as my next daily driver. But, I'm not sure if the tweaks are enough to really justify that move. Any thoughts? Anything similar that you like better? Thanks much.
