There are a few things that will make the Schweizer release a safer mechanism.

1 Inverting the release will eliminate all friction in the actuation.

2 Tow plane's release lever should be instantly accessible and have a high leverage configuration.

3 A careful dressing of the movable part of the release so that it is slightly curved where the capture slides off. This eliminates the increased force that the sliding capture generates as it starts sliding aft.

4 Tow pilots should include in their daily checklist a what if regarding rapidly getting rid of a kiting glider: where's the handle and which way does it go.

In Helicopters, the longline has two release mechanisms. An electronic one on the cyclic (stick) which can be push with thumb, and a manual one on the stick (brake type of handle). You are already holding the stick and the load is dumped fast, just a thought
