Kanewpadle, Takjr, Evilone and to a few others:
To me an expert is someone who knows more than most about the topic their discussing. The expert knows the issues involved, the various points of views on those issues, the pro's and con's of the arguments and the basic facts related to the discussion. The expert knows the weaknesses of their own position and that of the other guys. From what I can see by your posts - You guys are experts.
What you described as "experts" are really "know it alls" who don't know it all! As Mr. Eastwood would say, " A man must know his limitations."
I outta know I have a keen eye for spotting talent.
I enjoyed your posts...multiple guns, physical conditions/limitations, availability of a support system, ammo/time need to reload. I would add to the discussion the advantages of carrying the same guns and the same ammo if at all possible. If it was good enough for Wild Bill Hickock its good enough for me.
