There's a certain size I wouldn't mind seeing. They've got one that's decidedly small, a few average-sized dildos, and a few huge ones. I would love one that sits between the girth of the Spur and the Tex (or maybe just a bit slimmer than the latter), for days when the Tex feels like too much but the Spur isn't enough. Probably not much demand for that, though, so I doubt it'll ever happen.
Also, more colors! The flesh tones are nice, but the neon colors are also really pretty. Bright blue, anyone?
