YHR, you have hit the nail right on the head. The million dollar question is how one wires the switch up so that it stops at the right time.

Can the HL switch be used and if so how does one wire it up. This would be the best option as it would be practically a simple plug and play solution.

Must another switch be used in its place if the HL switch cannot be used and if so how will this be located and wired.

I feel a breakthrough in recoil technology it not far away.
