Come on, a hair trigger on a crossbow is absolutely not neccesary. Unless you're shooting in competition or a hit man or something. Heavy or a little hard to pull trigger is the safety harness in crossbows. Lighten it up too much, and it's like a rifle with a too light trigger. A little to hard of tap or bump, and BOOM! Duck your head Charlie, uh, too late Charlie. So, please Mr. Custer, I don't want to go.
My Xbows trigger is factory set and I ain't messing with it. But now when they invent the black powder fired bolt for Xbows, I want a remotely fired trigger from ten feet away. Only then is lighter better! LOL
