First off welcome John
It shoots well enough for me, but I want to add an overdraw
WHY????
Overdraws are IMO a creature of the past. They make a bow much harder to shoot consistently and accurately. With an older magnesium riser you may not be able to get the clearance for broadheads along the window that you need for an overdraw.
With the advance of carbon arrows there is no need to use an overdraw to lighten up an arrow.
I recommend a good prong rest - like a GKF or similar - and enjoy
