I have both packs, TFM and new TFM in a Selector based DBW install, but I have never really used TFM since I got newTFM up and running and further modded it;
I am limiting the planeset to the 1938 to 1959 timeframe so there is no need for me for more jets, the SAMs, helicopters like the Mi-8/24 or the Huey etc...
newTFM is simply copying the various respective parts into the respective folder (in my case #newTFM) in a selector based install, letting each part overwrite certain files if required...
the whole process takes about 10 minutes on my rig and if done in a safe temporary folder to check the filestructure first and make changes if needed is virtually bullett proof to do

as you mentioned CFS3, I know that was a little hard to mod; in my case, modding started with AoTP where there were some additions to the 1946 pack which introduced new planes like the XP-72 (one bird I´d like to see flying in IL2 sometime) and then of course came CFS2 with all its addon planes and stuff

but Il2 has grown into something completely different now.
but as you have said, once you get newTFM up and running, there is a few things to add still, but Simon has provided a great base with which to start...
btw, I looked rather silly myself when I first tried the F6F-5N against a Jap Betty bomber and pressed the trigger...the gunsound was there, but no tracers...
only when the bits and pieces started to come off the Betty, I realized what was going on...really great stuff..
concerning the HE-219, and other German nightfighters, ARAIK, some used a few tracers mixed with normal ammo, some did not, out of fear that using tracers might give their presence away to other gunners in bombers or the prowling RAF nightfighters; but mostly, late in the war, tracers were not used in LW nightfighters...
