Yeah i switched back from the PBO because it was too fast for my current physique. The change i would have to make in my technique right now, would be too huge.
So i just trained with it for 3h and my conclusion is, that i cant really play with this rubber. At least not close enough to my current level. I lose so much control for a huge catapult i simply dont need. This might work on bh, but even there the rubber is too fast for my taste. I didnt even need my arm swing to make decent bh shots. I hope the slower blade would compensate here, but it is simply enough.
On top i am quite certain that this single sheet has a bigger catapult than the other J3 i played with. I tested 3 so far but this one is completely overtuned in every aspect. Too sticky and way to fast, although we are talking about a 41 hardness rubber...
So i will definitly go back to my Big Dipper 2 and my Moon 12, though i would definitly liked something faster on my bh.
