You might also want to check your axle to axle length.My Allegiance was in the timing marks on the cams,but the axle to axle was off.The Binary cams are working,keeping the cams in time,but your axle to axle could change even though the cam marks are in time.You can also try a lighter point in the arrows,or heavier point at the same length arrow,just to see if the arrow spine is soft,or stiff.I would also recomend taking the bow back if you cannot get it to tune.Any shop that wants your business will work to get the bow shooting,if not,then find another shop!!!
