gtc, a few years ago i had to make the switch from longbows in the 50-55# range down to the 40# range due to a left shoulder and hand injury. The only thing that bothered me at first was my release. It just did not work as well as the heavier bows as I had a fluid draw and release and had to make a few minor changes. As far as effectiveness it will do fine on deer sized animals and smaller. In the last 3 years I have taken a 4pt. and a doe, but I limit myself to a 15 yard zone to make absolutely sure to get a good and ethical kill. When I deer hunted for the first time at the age of 14 in 1962 I used a 35# Pearson bow my uncle bought me and it worked just fine at the proper range so I have no doubt that you will be just fine.
