Welcome to the board! When I first started bow hunting, I passed on every young buck and every doe for the first 4 years. I had numerous oportunities but never took the shot. The only reason I never took a shot at does was because I only bought one either sex tag and didn't want to "waste" it on a doe. Looking back, I wish I would have been buying 2 tags, 1 either sex and 1 buck tag because I had plenty of opportunites during all those seasons. I would say, depending on how many 130-140 class bucks you see in your area, don't taken him unless there's not common. BUT, since you're new, you might just have to bend the rules a bit...depends on your philosophy.
