Ií m going with the Thunderbolt 390EXP119 with AFP injection and dual P mags. Should be a pretty nice setup. Lycoming gives you a $500 credit for the deletion of one mag, so the second Pmag only costs $1000. This makes dual Pmags a $1700 premium over std mags. From strictly spreadsheet logic, if I save 1 gal/hr, it will take about 300 hrs to pay back the investment. Easy decision.
