I advise buying 2 sets, a 9 and ten guage then mixing them. IE
a 10 gauge for the high 'e', then two very close guage strings for the b & g, and also having the low e almost as light as the a string.
(use the a string from the heavier set as the e) I find this helps with tuning and gives a smoother sound and feel to everything. Otherwise, there is too much disparity between the strings, xspecially on the low end.
