I'd go with 7 pot douglah x TS f4 and TS Moruga. That hybrid could turn out to be the hottest pepper on Earth. TS Morugas have gained a lot of attention since they scored the highest Scoville units. A lot of people are interested in TS Morugas for seed trades. Personally, I'm interested in a 7 pot douglah x TS F4. It's half way or less to stabilization. I'd also be interested in the F5s if you decided to grow them.
Sure, it's very prolific for a naga. I like the naga flavor over 7 pot. The Jonah is a heavy producer as well. The 7 pot Primo was crossed with a 7 pot and naga morich, which gave it a very unique look. I find them more tasty than Jonahs, which really are not bad tasting.
