If you decide to try scenting a pinky, a washed frozen thawed works best. If it's relatively large compared to your snake (my ringneck is just over 12" and a day old pinky is a pretty big meal), it helps to agressively massage it while it's thawing to break up the skeletal structure, especially the skull and shoulder areas. This seems to make it easier to swallow.
Once the pinky is thawed, I rub it all over one of my salamanders and take special care to make sure that the pinky's head is thoroughly slimed.
It takes mine about 30-45 minutes to get a pinky down. When eating something this large, mine is pretty nervous. I once checked on her too soon and she had just gotten the pinky down and rather than swallow, she regurged so I now give her a couple hours with the pinky before I check on her and I just put the cup in the cage and let her crawl out on her own when she's done. I'm hoping she'll eventually get more comfortable with the process.
Another big plus to having a pet salamander (they're interesting captives in their own right) and feeding scented pinkys is that it's relatively easy to provide a steady supply of food especially in cases where salamanders are only out and about seasonaly.

P.S. I keep my ringneck at room temp (my room fluctuates between the low 80s during the day to the low 70s at night). She does not seems to have any difficulty digesting her meals at this temp and is on a biweekly feeding schedule.
