Kind of a strange comparison, don't you think?
It doesn't sound like you need a high din binding if p12s sufficed, so the axial should be just fine. Even if you did need something with more housing, you could easily get something like an FKS 155 (or even a p18) for at least $100 cheaper, and they're tried and true (although the Jester has good reviews thus far and doesn't seem too shabby, except for the price tag.
