reducing drone

You're killing me, Steve!!!

The drone, I would guess, is caused my the lower volume of air going through the exhaust. Increase air flow -> increased tone/volume of exhaust. The resonators are there, I believe, to reduce that drone, at the cost of upper-RPM goodness. The 18" resonators won't be as loud and deep as non-resonated, but drone will be worse. You should be right in the middle with 12" resonators.

My belief is that in order to get your ideal tone at 4-6k RPM, you have to be ready for the 2k RPM "drone".

None of this is fact or professional opinion, btw. If you have any issues, I'll gladly take the exhaust off your hands!
