if you come to full draw and the cam hasn't rolled over yet, that's a real good sign. (just adding a little humor)

and i just want to add there's nothing wrong with an open stance, a square one, or a closed one. some of that depends on how you're built and where the bow wants to drift when you're aiming. assuming proper draw length, you determine your stance by drawing, aiming, closing your eyes for 8 seconds and then opening them to see which way the bow drifted. up and down doesn't matter here, just right or left. you then correct this issue by correcting your stance. this needs to be checked monthly because form is not a static thing, its dynamic.
