I have a pair of babies I got from Jerry as well...they were adamant about NOT taking pinks, scented or unscented for the first month I had them. I broke down and offered them some cricket frogs (Acris sp.). After 3 meals of cricket frogs, I offered them scented live pinks (scented with cricket frogs), and they took them. A week later I offered them scented pinks (live)again, and they took them. This last week, I offered them unscented pinks, and they took them.
Basically, I just kept a few frogs frozen in a deli cup. At feeding time, I'd thaw them out, add a few drops of water to create a "broth", and let the live pinks stew around in there for an hour or so. I did this at night, which is important. The snakes usually took the pinks within 15 minutes or so of them being introduced.
Hope this info help, scenting is the way to go, after a few meals of scented pinks, they'll get the idea and start taking unscented.
