Single parallel
coils mounted high center with 2 or even 3 AFC slots wide open for my LDLH's are starting to win out as my preferred build on the Nuppin's now days. Easy builds that are all but foolproof after trying several wire gauge combos. I've been doing my parallel builds with two wire gauges... 24/26; 26/28, 27/29, 29/32, etc with both standard and twisted wires for the advantages of both gauges, plan to try some with ribbon wire as well, flat and twisted. Could be they'll end up in all 6 of my Nuppin's.
Might be worth the effort to try one or two in a Nuppin' (especially if you are a lung hitter) to see if they also work well for you.
