I wanted to try something new and bought my '07 Allegiance.

I've only shot about 1500 shots so far. As for cam timing it'spretty much anon issue. Both cams are slaved together with the cables and as a result rotate in sync.

You haveBowtech,Elite, & High Country. Although, HC calls theirs the trinary cam. Elite calls theirs K8 & Envy.

With the Bowtech you just check the dots on bottom and top cams to check timing. Upkeep is like any bow. Wax the string, check to make sure everything is tight.
