[coach/dad voice] “What’s better for accuracy is Practice.”
“Better” is a tricky term. What works for me might not work for you. Particularly I f you’re still developing technique, the p88 is more consistent, because it’s one smooth curve. P28 has enough different parts, that you have to learn how to use it from the heel vs toe. personally, I have trouble with the p28 keeping anything on the ice. It’s great for quickly elevating shots, but if I want to make a hard tape to tape pass, there’s a good chance it’s getting to the other player 6” or more off the ice, which isn’t helpful to anyone.
Do you play with a ball? (Maybe I’m confusing your with someone else.) Shooting a ball with a p28, for me, would put it in the parking lot. It’s so open and twisty. You might be able to get some wild lateral movement, but everything is going to be waist high.
