ideally, I'd love to find something that's a combination of features from current bad-dragosn - with a knot and length like Rex, with a tip and ridges like demon-dick, and curved. Some come close, like spritz, but not quite the prominent knot like Rex. Any ideas?
Well it's not curved but if you got it in soft it may curve inside you I would recommend the kippy? It has spines and a knot it fits most of the bill...check into that model
