Definately try an AA before you buy it JB....there was one at the last Fall KC and I was very tempted but they are done for guys with hands/fingers which are huge...my take was that I was as likely to break my fingers as much as anyone's face if I had to use the dusters....and using the blade would be very uncomfortable for me because of the too wide duster fit...

As a fighter "for real" I think the Jackhammer or SJTAC which you have is pretty much ideal...light and fast and easy to carry with enough blade to do all the standard stuff...for that matter I also think a RMD is ideal as well...but I have a JH and SJTAC because for me they are the closest so far to ideal that I can afford in INFI and the pommel crusher is a good design.

Personally I would rather have the bolt on accessory which makes a "D GUARD" type duster for comfort....Randucci has done some nice ones on mini SHSH's....and I decided to go for a 3B2 as an option to the JAC's as I might ask Randucci to make me a D Guard for this knife like those done on his knives...and the 3B2 feels just like a SJTAC on speed and comfort...
