RE: switching to longbow
Welcome back.
I'd suggest checking your state minimum requirements for big game as far as draw goes, and go with that the first year. Around here it is 40 pounds, I think that would be a great starting point.
If you want to go with a new bow, I'd take Arthurs advise on the Viper. If your draw is 26 or under, I'd go with a Howard Hill bow that you can get for $200.00. Or you could go the used bow route and get something. try the tradgangs classified.
