Brian, I think you got the most important part right already in your first sentence. If you do that, "put the arrow in the kill zone", I think you'll be OK. I use a 115 gr., very old Bear Razorhead this past fall (the optional bleeder blade adds 10 gr.)and took a very large bull Moose here in Maine. I choose the 2 blade option because I could only handle a 53# bow at the time and was a little concearned about penetration with a three or four blade head.
A sharp 2 blade will do the job nicely, but if you can shoot heavier weight, I guess the more blades the better (unless you hit bone).
I grew up in Connecticut, or at least started to. Shot my first deer there in 1959. Where in Conn. are you from?
