P28 is a nice passing blade if you sort out where the heel to middle release point is. Usually it’s possible to launch a saucer pass heel to toe, especially with the degree of loft on blades like the Drury. I’m pretty sure that’s the main reason for there being so much loft on the blade. The P28 still has vestiges of that origin: it’s an open heel curve until it turns into a mid-toe curve. The rub lies in the aggressiveness of the rocker on the toe. This means you can’t wait until the puck is at the toe to launch a sweeping saucer pass or shot starting from the heel. You have to release before you reach the toe, just beyond the middle of the blade.
Before you go trying different curves, see if you can expand what you’re comfortable with using the P28 for. Just practice the saucer standing still, super soft motions, almost no pressure on the stick. Do a few sets of five or six pucks in a row and see if you can feel where the puck wants to release. I did this when I was struggling with my Ville Leino SE16. It’s basically a Kovalevized P28: lower lie, max-length blade, but similar idea. Once I found the sweeping sweet spot I didn’t have fluttering saucer passes anymore. My shooting also improved, so I could finally shoot from either the heel or the toe, no problem.
