I am a kukri kind of guy as well...!!

I would also be up for something large with a Regulator grip, along the FBM style of thing.

The Mega Regulator or Super Regulator or Regulator XL has some merit as well.

I am also another that is enamoured with the idea of "magnum mudder" grips...!!! Attached to an appropriately sized blade !!

At the other end of the spectrum, the Skeleton Key is one of my favourite Busse blades, I have a couple but one I got from Dave Brown (used by him for some of his 1/4 punching escapades) is probably my most carried and used blade (as despite my best efforts the ASH1 just does not work as a neck knife!!!!!) . A similar "long" thin blade from you would be a must have for me..!!!!!
