At Blairstown Airport we loose about two minutes each time switch between Tost and Schweizer tow rings. I'm wondering what is being done at other busy operations, there must be a faster way. Help!

I make the ropes for the Cordele contest. We have towplanes with Tost hooks, and towplanes with Schweitzers.
I put both rings on the rope end.
If you are talking about glider end, we have not tried that, but it should work.
