I have my own perspective on this and am going to give some advice based on 35+ years of shooting compounds and bowhunting with them. Please bear with me as I have no ill feelings toward anybody.

Being a new guy I would say that in most cases you should not even be thinking of shooting longer than about 30 yards. Those of us with lot of years behind us have learned this. It's the inexperienced that consider longer shots---and 35 yards is considered a long shot in bowhunting. Exceptions might be hunting out west where spot and stalk is more common.

Now, that being said, more poundage does not automatically mean faster arrow speed. Depending on how stiff your arrows are spined for your bow you may have to use a stiffer, heavier arrow if you turn the weight up. This just about negates the gain in speed you are after.

And I'll tell you this. There is not a bow made today that shoots an arrow fast enough, that sighted in for 25 yards, only drops 2" at 35 yards. It is quite possible to take a bow shooting 260-265 fps, set a sight pin for 25 yards, and shoot that pin effectively on deer sized game from 5 yards to 30 yards. The high point would be about 2" at 18 yards and the arrow will drop about 3" at 30 yards----4" at 32 yards. I know. I've done it. It's the kind of things I do.

The othr guys covered the stiff muscles and cold weather very well. Also sounds advice was that of having better accuracy at a lower poundage. Anybody that would dispute this has a testosterone problem or is just in denial.
