IF you decide that keeping stocks of all 4 color/gauge combos (black-silver / straight-butted) is too much inventory, I would eliminate the second color before eliminating one of the guages.

I other words, I would just stock silver OR black, in both 2.0 and 2.0/1.8 guage.

If I am on a long trip, I am not going to give a crap about the color, but I would prefer that the guage matches the rest of the wheel.
