I've tried the Malkin, McDavid, Barkov, Hossa, Panarin (supposedly a P19 clone but plays just like a P92), P38, and Backstrom curves. Please don't tell my wife. I've talked with Geppetto a number of times about trying to find something like a loftier P88. The Backstom has been the closest in my opinion. The MacDavid is sort of similar to what you're looking for as well, except that it's a 4 lie and that has been a very difficult adjustment for me (it's based off an old Iginla Jr curve). But it shoots nicely. I'm just trying the Barkov right now, which has a bit of loft at the heel like the Darby and a little bit of hook at the toe, but overall is actually a fairly straight curve. I dunno, I feel like I've exhausted all of his options for someone who is not a toe curve shooter, so I might just give up and stick with the P88 as the trade off with the P92 or P90TM is better shooting for worse passing, which isn't worth it to me.
