I switched a couple years ago from compound to longbow. I actually missed a couple of deer the 1st year and was haveing more fun than ever.
The only "con" that I can think of, and its already been mentioned, is the distance that I feel comfy taking an ethical shot. The farthest shot I ever took w/ compound was 32yrds. But 99% of my shot were 20yrds and under. Which is still in "my comfy zone" w/ my longbow. So with that said, I dont feel that distance is significant for me in switching over.
All I can say is dive into it feet first and have yourself some fun.
If its about killing everything that moves, then may not be for you. But, IF, it is about the journey, you are missing out for sure. Good luck with whatever you choose.
