It is definitely stiffer than the PSL that I had been using but not uncomfortable. I have all mine strung up with full poly set ups in the low 50's with the vibration stopper dampeners and can't complain. I think the microcore filling really helps counteract the frame stiffness. I can't think of any other racquet I have used that feels quite like this frame. I agree that you really have to flatten out your shot if you want to blast someone off the court but I am now hitting more consistently deep in the court off both wings when backhand was really suffering for through my last couple of frames.
