P90TM is similar to P30 in that it was subtle but had some performance features. I'd say P30 was a P88 with a little more rocker and a kink on the bottom of the toe. P90TM is a combination of the three main retail curves. It's a flatter rocker and wider blade like the P88, with the heel twist of the P29, and the toe beak of the P28. And the same Lie5 as the P30. As someone who used both, I'd say that if you liked the P30, you'll probably be happy with the P90TM. I personally love the P90TM, much more than the P30 (but that may be the stick itself too). The Bauer P14 (and I guess Sherwood PP14) had a similar shape but it was shorter and not as much kink on the bottom of the toe. I wouldn't call it the same.
