I would suspect that your arrows are underspined for the setup. To find out if that is the problem at no cost, you could back off on the draw weight and see what happens to the grouping with the 125s vs. field points or the 100 gr. broadheads. If that clears it up, then you can decide whether to shoot at the lower draw weight, or get new 75/95s. The Cybertec is a pretty high energy bow with a lower brace height. 55/75s are about on the very upper edge of their spine range at your specs, I believe.
