That's a thought I had, but its mere speculation at this point. I've spent some extensive time searching, even talked to a few vendors and all I come up with is that they seem to be interchangable but I haven't come across anyone that has put it to the test, and at $1200 new for the pair I can understand why. Maybe I should try reaching out to Beisan.
