...I will say that concave wing felt terrible in my FH grip.
That worries me since I throw my Rhyno forehand just as much as I do backhand.
If this feels too different from regular Rhynos, I'm not really interested. I have two heartbeat Pro Rhynos that are ridiculously overstable, and I'll throw those instead if I really need this slot filled. At least the mold will feel the same.
