I will say this becausei honestly do not care what anybody says,Bowtech has enough speed engineered intothe bows that they produce that even if the strings are fully loaded they will produce excellent speeds.As far as timing issues i don't really think this is even a discussion.I bought my 2005 Allegiance in Feb. of 2005 and shot this bow well over 1,000 times and have not had any "timing " issues.As most are aware ihave had other issues that can and has happend to "ALL" bows at some point or another, and has been graciously been taken care of by Bowtech and my well respected Pro Shop!!!!As far as the MZE on the allegiance i ave had "zero "problems!!!
