i'd go with waiting as well they've got sized in between i know that.i found it a little harder going from a 6 to a 4 so i don't know what to expect for a 2.did you try wetting the gauges themselves?
yeah, i have this vitamin e swiss colagen shit that my mom bought, it lubes really well, so I use that with every stretch, but from a 4 to a 2, forget about it, the taper just won't go in.
