Bratis Labs
I do not know anything about their winny. I was looking into geting some of their var. Poked around and the women over on the womens board swear by it (Brick girl etc.). I highly recomend you go over there and take a look at brickgirls photos she is fucking a bad ass. I know it is no help with the winny question but at least you know they make a viable product.
