Tomorrow I'm going to setup my floyd rose equiped jackson and to change it's string guage.
I'm going form 0.10 to 0.11. I have 2 pair of strings one is Rock n Roll power slinkies (0.11, 0.14, 0.18, 0.28, 0.38, 0.48) and the other is Skullbusters Misfits (0.11, 0.13, 0.17, 0.28, 0.38, 0.48). The question is which should I use first so then I change strings I wouldn't have to do setup again (there is difference in string 2 and 3). BTW I'm detune 1 step (D, G, C, F, A, D).

Probably not going to make any difference. A hundredth of an inch on two of the strings isn't really going to affect the setup at all. The brand/construction of the strings would matter more. I bet they'll both be interchangeable.
