i don't play any right now except for the ceramic nazgul for high gain downtuned chugga chugga (and the dimarzio blaze neck in a 7string).
it's teles and regular AWG42 Humbuckers for me most of the time.
i have some Bill Lawrence/Bill&Becky L500L and XL laying around. not sure if A5 or ceramic. i liked them quite a bit and i want to reinstall them in something soon...
also laying around but not tested:
SH-16 hybrid (actually was good for the short test drive i had it in), perpetual burn, pegasus, full shred.
the duncan custom 5 was boring to play. especially solo stuff. i guess too lil harmonics, but tried it only in one guitar. (still own it)
i like the screamin' demon in the right guitar, so go figure
do have some half ass tested (or never installed) ceramics for the high gain stuff laying around (dimebucker, jupiter, SH-5, blackhawks). <- but only 1 or 2 of those are allowed to remain and i always keep a pair of EMGs 81/60.
it will be a hard decision between the L500s, dime, blackhaws and jupiter rails!
it would be easier to make more guitars, so i can postpone that decision
