I'm also about 3,5-4.0. Tell me something about playing with Phantom on this level. Is it hard to generate power?
At first it was. Sweetspot felt small and balls were going in the net more. Then I tinkered with string type and tension and I think it is OK. Not powerful but adequate to put a ball away with some level of authority. I tried weight in the upper hoop to get more power and expand the sweetspot but it made it harder to swing and time.
