I'll start off with the fact that I like thin handles. I have big hands but they are meaty, so mags just take up too much room for me. I have made my living using hand tools for the better part of my life and I would have to say the Fusion design is one of the best out there. I keep a grip on my tools, so I really don't have the issue with "pinky burn" that I read so much about. The ASH 1 handle design fits like a glove, but doesn't give versatility for as much multi grip as I would want. The SFNO was a grail for me, that was until I got one. It is one of the sexiest looking knives I've ever seen, but is just plain uncomfortable to me. It has been quite some time since I owned one and can't remember the specifics, but I remember selling fast after using them.
Personally I like the EU, Fusion, TAC and the newer handles on the DSSF and BOSS Jacks the best.
So out of the choices, I would recommend:
FSH
ASH 1
SFNO
