Hi Geoff

There could be arrow movement side to side with just the one screen, which I always thought was a weakness of the ProMat system. The two screens will ensure that the arrows are held quite firmly without any sideways squirming at all. The screens will have to be stretched fairly tight over a wooden frame but not overly so - just firm. The target face clips to the front screen using our club "patented" system of two sharp hooks joined by a rubber band. Works well.

The only thing that will require some tuning will be the buffer springs and I will be trying a variety of different tensions. Having arrows bounce right back out would be highly amusing for a while but I think it would wear thin quite quickly. The aim is to get the right spring tension which will allow the backstop to move back against the springs and then ease forward again slowly.

The real key to this "system" is the arrow point. A sharp point will enter the backstop and eventually you will get pass throughs and be no better off than with all of the present systems. You need a point that it rounded enough to pass through the mesh without damaging it and which will not penetrate the backstop material. Will my point idea work? Dunno, until I get some of the Dupont material.

I'll keep everyone who is interested, posted on the results.
