As you can see by my sig. I currently use 340 FMJ's for my hunting set-up (heavy arrow by some standards...which I prefer and will stick with) But the "friendly backyard league" I shoot in with my friends is starting soon, and I was thinking of shooting Fatboy 340's for that. Can I get away with just buying another sight and setting for the fatboys, so I don't lose the settiungs on my hunting sight or does the change in arrows require a change in tuning(rest, loop height,etc.)BTW I'm talking about the Vulcan. No Target bows Allowed! By penalty of Beer Tab!
