You've read what everybody has said..."Get the Anvil-30." Well, that is what I did and placed it atop a Two Vets V2. I am extremely pleased with the RRS gear I have purchased. In addition to the Anvil 30, I have a couple of RRS bipod clamps that accept either Arca or pic rail...great kit.
The Two Vets V2 is impressively heavy duty, and I added a 1/4-20 threaded eyelet to one of the threaded holes on it to hang the padded RRS head pouch from. I also put together a shooting plate with a flat bag for shooting rifles without Arca rails. Until I need something better, all of this slides into a folding lawn chair bag. Works great. I think I'm going to be happy with this setup the more I use it.
