For stiffness, the UPK will be stiffest of the four. The PProV2, TPK and Rev should be comparable with the TPK a bit stiffer of the three and the Rev the least stiff, if splitting hairs. But stiffness is not the key, the key is the repulsion you get from the PProv2 and TPK shaft. You get more with less effort. It's a Toray 40T wrapped in the latest Mitsubishi 80T "max repulsion" graphite creating more synergy which in turn makes the shaft produce more power than previous shafts.
Update: going forward, all Panda Power rackets will be using the new "40T/80T" shaft because it's the best that Panda has found. It's more expensive but worth it.
ZM62 already gives me more for less... can't imagine the craziness if combined with this new shaft...
Just so I don't miss out on this train... I should contact my Canadian supplier once DinkAlot has received his shipment? Also, it seems like people are requesting raquets with specific weight/balance point? Or is this just luck of the draw?
Please wait, until the rackets are actually here, hopefully in 2-3 business days. Of course, you should always request your ideal weight and BP. We will try to fulfill your order as best we can, thank you.
Man, you guys need to read more carefully. Panda said: if splitting hairs! Panda splits the hair "this way" (PP being a tad bit stiffer). Maybe you will split the hair "the other way" (Rev being a tad bit stiffer). It's comparable and a variety of factors can affect the stiffness and the two greatest being: 1) head weight/BP and 2) the manufacturer's tolerance standards when creating the shaft. Anyway, this is why Panda doesn't like answering questions that are comparable with some thing definitive: Panda gets replies like yours. So Panda is going back to his original ways of being accurate, by being vague (when it is warranted)... ...So, the question about which racket is stiffer, the PProV2 vs. Rev? Answer: They are comparable, everything else being equal. Your mileage may vary and no, Panda won't split hairs if pressed because he doesn't want to repeat a post like this.
Dink's concept of a racket description is like Napolean's concept of a constitution: It should be short and obscure.
LOL! By the way, UPDATE: rackets should be in Panda's paws tomorrow or at the latest Monday. Will update all tomorrow...
Update: My order has gone in to the Panda, but there may be a couple of spares when the dust settles.
