Fabio, I agree, you are doing fine.  I THOUGHT you were either talking about the WarDog or the Regulator and I was leaning more toward the WarDog.
Like JJ, I don't know about Dan's reason for the WarDog, but I also am glad he made it.  IT IS NICE!  I also have the Busse Combat version, the WarDog HACK.  THAT is a deeply hollow ground lightweight blade.  I think it will make a nice fighter if you round off the rather square shaped pommel.
I rounded off the pommel on my Scrapyard Wardog and made the choil larger for my fat finger and I LIKE IT!
If I had to have only three blades, I would have a hard time picking but the list would draw from:
1.  BWM
2.  911
3.  Regulator
4.  BullDog
I would probably choose either the BWM or the 911 though, for the BIG jobs.
The medium would be either the:
1.  Wardog
2.  S5
With the Wardog being the more favored
Small would be:
1.  Mud Puppy LE
2.  311
This would be a VERY hard decision but would lean more toward the Muppy, because it's got my JYD # on it and I like the blade shape and the mudder grips are really nice and balance is really great for me in this size.
I said three blades, but actually there would be 4.  The Cupidvore would be around my neck of course.
