Not trying to hijack this post, as this is along the same lines, so I thought I'd ask - has anyone here tried Bi-Delta "Rain Vanes"? 3Rivers has them, and I've been tempted to buy them. Along the same line as what you are doing Trooper, but supposedly, you can shoot them off the shelf because they have "micro-groves" cut into them, so they are supposed to resemble feathers, and supposedly get softer with every shot. I've gone back and forth for months over whether I want to try some.... but haven't yet.
All the best,
Glenn
