The 6 grind is a great option when compared to the regular grind IMHO. I would also go with the squared hilt and thumb notches. I have a blue/red micarta and it is an awesome handle material. For a fishing knife a wrist thong is handy in case it slips. So here it is for me:

Model 7-5
SS blade
#6 grind
NS squared hilt
Thumb notches
Wrist thong
All red spacers
Blue/red micarta

I might be over the 5 options, so Cap can confirm. If so, I'd drop the NS hilt for the brass.
