I have both light and heavier 16's (6/3 and 6/12) and like them both equally well. Both are well suited for different tasks. As for the RBL, no other gun compares except maybe a new Ugartechea, and they don't come with the case and other options, and they aren't made here in the U.S., which is a huge selling point imo. Was it a success? I don't see how it couldn't be considered as such.
