I want to be clear, I am not against fast bows, heck speed (with an appropriately weighted arrow) will allow you to shoot a heavier arrow at a good speed increasing KE/Momentum and penetration. That's a good thing.
I just hate to see someone that may be switching from wheels, or maybe someone just taking up trad for the first time who may be reading this to think that these bows are capable of things they are not. A really top flight glass recurve, lets just say 50# @ 28" drawn 28" with a 500 grain arrow, shot with fingers may shoot in the mid to high 190's. (I see very few that will do that, most will be in the high 180s). An average glass recurve of the same specs may shoot an arrow in the mid to high 180's (but more likely in the high 170's).
I've read Blacky's reports in TBM on all the "latest" bows that he has tested (with 9 gpp I believe) and non have made it out of the 190's and most don't make it into the 190's.
Sure bows are getting faster when you read the reports...arrows are getting lighter, strings are getting lighter. I imagine you could really get one sizzling with 6 or 7 GPP, and a 6 strand super string with no silencers, drawn 30" but what would that tell you? Nothing really.Cause most of us don't hunt set up like that.Heck you could even go with a 75 grain broadhead instead of a 150 grain head and pick up more speed.
Find a bow that suits you, fits your hand, draws smoothly to your draw length, is quiet upon release, shoots where you're looking, doesn't pinch your fingers, has the right physical weight for you, is visually appealing to you, and if it's faster than average that's all the better, but if it's not, and you can't kill game with it, it's speed won't be the reason.
