Cool, the Emax is known to be hard on alot of things, scopes included. Lord knows w/ all the V-zones out there and now L-zones [lifetime warranty both] there are bound to be some problems. What scope[s] does your buddy Dereck Middleton advise?? Certainly not Excals as they constantly bad mouth each other, one w/ 25 yrs experience making xbows and one w/ 25 months. Maybe Middleton will bring out a scope when Excals patents expire on the V-zone, lol.
