What's really nice about today's compound bows is that you can shoot a fast arrow AND have plenty of KE to burn. My set up last year I was shooting a 355 grain arrow 318 fps, producing nearly 80 pounds of KE. I think that's more than enough to do the job. Heavy arrows and KE aren't the issue they once were, today's bows are so incredibly efficient.
And, if you happen to have a speed bow, you can shoot a heavy arrow fast. Right now I'm shooting a 450 grain arrow 290 fps, generating almost 83 pounds of KE.
In some cases, it's all about KE. Traditional shooters, youth w/ low poundage bows......But, the nice thing w/ today's compounds is you can shoot the speed, and the KE will be a product of that.
Efficient the new compounds are but I see allot of arrow set ups where they are not. People want speed, speed, speed.
I could be wrong but I'm thinking from 10 yards to 15 yards (your avg. shot in the woods) these arrows coming out of these new compound bows aren't hitting there top end speed yet being there still picking up speed and KE because of the huge let offs.
