| First things first you do not need an internet forum for your arm; you need a doctor.
As for the equipment; have you measured the draw weight of the limbs, or just read the labels? You mention that you have managed to get a decent bare shaft tune at 30 yards for the first time, what was happening with the old limbs? Arrows showing too stiff, too weak or too random? I'm asking this as marked weights on bow limbs are not necessary comparable, particularly at draw lengths other than 28 inches and between brands.
Next are the two sets of limbs the same length? With a short draw length like yours longer limbs just won't bend enough to work efficiently, so longer limb poorer cast.
Finally if you manage to get your arm sorted I wouldn't worry about sight marks or tuning for a while just relax and enjoy shooting for a bit until the new year as you are unlikely to need to shoot 100 yards during the indoor season. |
