I'm not sure if spins-offs are your problem, but I've had spin-off trouble with similarly designed heads, and I'm done with them. For now, I'm strictly a Muzzy guy. They are the best balance I've found between pentration, holding ability, and quick fish removal. I don't have penetration probs with them, and you can't have a spin-off.

For any new guys reading this, a "spin-off" is when a fish thrashes and spins after being run through and, due to the design of the bowfishing tip, causes the point to rotate on the shaft, loosening the head, and finallydisengaging the barbs.The fish then comes off the arrow, laughs at you, spits in your general direction, and swims away as if it wasn't just impaled on 32 inches of fiberglass, never to be seen again.

Since there are many point designs out there, the rule of thumb is this...
If you need to twist the barbed section of the point in relation to the shaft in order to disengage the barbs, a spin-off is possible with that configuration. If the barbed section of the point stays stationary in relation to the shaft while disengaging the barbs, then a spin-off is impossible.

Penetrator...(The whole top 2/3 turns)
