We use ropes with Schweizer rings on both ends, then have a about 4' rope with small rings on one end and a rope loop on the other. It just loops between the tow rope and glider.

Believe that's what makes it slow. Try ropes with both types of rings on the glider end, as Hartley does at the towplane end.
But this means that normal wear will be on both and a break will lose both ring types.

The incorrect hooking up of a small Tost ring on a Schweizer tow hook is a known hazard of this practice.
