RE: Different releases...different arrow flights
I've pretty much always found single caliper releases will shoot differently than dual........they can tune differently too as the string or loop leaves the jaw/s at a different rate or position.
If I remember correctly my Scott Wildcat will shoot left of where my Scott rhino shoots becasue with the Rhino the string loop pulls straight away and with the Wildcat it must clear that one jaw bump.
No biggie. As long as you verify tune with the new release and plan to use it exclusively just re sight in.
