I need to play the PT2.0 more, but initial feeling to me was that compared to the Blade 18x20, the PT feels more connected, more solid, more accurate and about the same power. I struggled with my serve with the PT. The Blade makes it easier to get a kick serve going, but I think I’ll probably serve better first serves with the PT once I get the feel for it.
I agree with
@jdeloach that the PT feels faster to swing.
As much as I enjoy using the v7 Blade—it's a great all rounder and supremely comfortable, it has a certain vagueness to it that I find a bit confidence sapping at times. In another thread, somebody called it a 'rubbery' feel, and I think that's a good description. It's totally different to the clear, direct feel of the PT2.0 or 6.1 95 (my previous racquet), and I think I enjoy the direct feel more.
