Not serpent, but I suppose the general Idea is the same.

This is a great idea, but I dont like the idea of it being here as just thinking of the pressure being off centre, and pulling the slide up... Wear and all, but then the servo will ballance it out, would actually not cause a problem.

Anyone else have another idea?
