By the way, I had been using my pureHA135 stab bolted straight on the fuse for a couple of months now, but I’ve added a +1 degree shim from the set at Tail Angled Shims for Takuma Hydrofoils by walter - Thingiverse and I think it’s overall better for me, at least on the evo175, with my back leg getting less cooked, and a better low speed stall, low speed pumping suitable to the low energy conditions.
Just need to trim the excess plastic at the end of that shim, but that’s a 10s job.
