The one and only deer that I ever shot with a compound was with a Thunderhead 125 back in the early 90's. It was an old round-wheel Jennings,60#,65% let-off, so probably slower than a good recurve. Shot the buck at 27yds. slightly quartering. Complete pass-through, never did find the arrow. Massive blood trail, 80yd recovery. So, do Thunderheads work? Yes. Are they my first choice? No. I have a basic distrust of replacable blades, especially when bone hits are involved, but then I'm a skeptic anyway. I consider that shot lucky, and have used nothing but Razorheads, Zwickey, and Grizzly since. JMO. Good luck, I'm sure yoo'll be fine.
