If a P90T is in fact a Benn clone, then it is not a P30. The P30 is a P88 with a kinked toe being the only change to the curve (the rocker is different). The face of the blade is closed until you get to the toe, and the curve is a true mid. Bauer's Benn was more of a P92 variant, with a heel-ish twist and straighter blade of a P92 until you got to the toe where it had a sharp curve and kink to it like the P28. The Benn had a higher lie than the P30, again closer to the P92 but not quite that high. The toe was roughly the same shape and not as tapered as the P28, closer to, you guessed it, a P92 with a more square top but rounded bottom.
Compared to the pic of that pro stock P90T, the Benn was more open throughout the blade and had a rounder toe. That P90T does look very much like a P30, the difference being the toe isn't quite as kinked at the bottom. I'm hoping they bring it to retail, as it really seems to be a full size blade version of Bauer's P14.
I do not have them both in hand, but did compare them side by side at my LHS with the new Bauer Pro Custom samples.
