This may sound weird, but have you tried trimming your pubic hair? If you like the saddle overall, it might be possible to control the chafing without losing the saddle you like. Sometimes hair can be a problem. (search "brazillian" or "Lawn" for a couple threads on this issue.)
You can also try using Astroglide, which others on this board find helps in the more personal areas of the anatomy while butt'r handles the rest. (search "astroglide")
