I believe that the speed bows definately have their place out west, alaska, and africa. In a treestand in IA/MO...not real important.
No argument from me! I hosed myself this year on a dandy buck in S. Dokata. I had my 78 pound bow in the tree with me. It was cold, I had been in the tree all day. I had the buck and a doe drifting in and out for two hours towards the end of the day. When it came time to draw, I couldn't pull the bow back (tried eight times). I had been so cold; I was literally shaking in the tree. My muscles were completely fatiqued. First time that ever happened to me...
The next day, I hunted with my 60 pounder (killed a turkey that morning).
I amlearning more and more that there is a time and a place for everything! Having the right tool for the task at hand is also critical. Hunting ducks with a rifle, for example, is not the right tool for the job. It just doesn't make sense to use a massive draw weight bow in tight cover were shots are extremely close. But, out west, Alaska (caribou), and Africa (buffs/hippos/elephants)...whole nother story.
Shoot me a PM when you're heading back this way.
