Hi! I'm the same guy as on BladeForums with this name.
It's a great question Dan – thank you for asking. Here's my vote:
1 = Basic handle (new style)
2 = Regulator handle (rank would be 1 for larger knives)
3 = Mudder handle
My first experience with a Regulator handle was on the AR 9.5, and I'm glad I ordered one! On heavy knives, this handle definitely gives more control. I'm guessing the 1311 would feel better with a Regulator handle (by "better" I mean the user would have more control of the relatively heavy blade). I have a BB13CG, and a Regulator handle would definitely feel better, especially with all of the forward weight.
I'm glad the site is up & running again; I'll try to hang out here more often.
