Yea, ya gotta shoot them both. I have made a bunch of selfbows and love many of them; some, not so much. I also shoot a few glass bows now and again and hunt with a Jess Stuart recurve now that I shoot so well, I doubt I will ever give it up. Both will kill a deer so shoot the one you like best.
One thing about a short hickory like that, it has to be well designed and crafted. Tiller is everything on a wooden bow. If it is pulling 50# but stacking like hell the last 3", then it is likely slower than the 40# recurve. If it has a lot of set because it is too short, then even more so.
