If you can’t elevate your shots consistently with a p88, don’t spend money on new sticks and curves, find someone who can coach you for a few hours on how to shoot properly.
I’m not trying to be condescending, but not getting the puck up consistently, you just need to practice. A new curve might cover that for you, but it’s going to leave some other glaring hole in your game.
Shooting a ball wit a 28 or 92 seems downright wild. I feel like it would fly out of the rink on everything.
