Before you potentially waste some money on more broadheads, make sure it's not the arrows.

GoldTip XTs and Hunters are usually wobbly to begin with. That's whay I do not recommend them unless our budget is super tight.

Also you should install your inserts with broadheads, spin test, then let them "set up"...not field points...field points will often show little to no wobble but broadheads will show up ANY imperfection in the arrow, how the insert was installed, or the insert itself.
