A basic jet modpack (called Jetwar, adds Mig-15's, Mig-17, F-86's, F9F) is already included in the DBW 1.71 Superpack, so all you need to do is to install some extra planes if you also want to play Vietnam scenarios.
DBW has very good expansions and most importantly
very few bugs. Disadvantage: no new AI which was introduced by 4.12 patch, no taxi to takeoff feature. Many mods were not reworked for 4.12 so with DBW you can have the most mods in any IL-2 intall.
