RE: String wear
Here's a hint. I made a string for a Maxpoint and used as many strands as possible and still fit into the cams. Served it with .030" Halo. Should last a couple of hundred shots or more. The Maxpoint has no let-off. If one wanted to it the serving could also be padded with a length of serving. The whole point is to give the claws as much surface area as possible.
