594 & CU24

[Apologies if this comes up frequently and I missed it... my forum-search-fu isn't so hot today.]
My latest workhorse is about to get hot-rodded and parked in standard C# as well as drop C. I could math out appropriate sets, but since a chunk of the forum can probably tell me off the top of its head, I'll just ask...
What gauge(s) would you recommend I roll? My primary concern is proper tension on the 5th & 6th strings for high-gain mayhem.
Thanks in advance!
