P3: Tweener, doesn't really feel all that suitable for putting IMO and neither does it feel as good in the hand for driving as a Dart. Decently stable/overstable, but you have to have pretty specific needs to put this in the bag between something like a P2 and an mildly overstable mid.
P-PD2: Mine is one of the good ones (early on there were some that were quite flippy from the start), and it's definitely overstable enough to be a proper PD2. The glide is pretty non-existent and the fade is hard, you need to be able to push it hard to get good distance out of it. As it beats in more it could possibly get longer, but it's hard to say. I do like it a lot for distance into stiff headwinds though.
Going purely Discmania is definitely a possibility, I basically did that some years ago and nowadays it's even easier. A couple of beat D-P1s for long long spin putts and short understable drives, a bunch of P-P2s for putting and driving (with very beat P2s you could skip the P1s totally), a few D-MD2s to cycle around neutral and understable (also takes care of finesse mid duties), flat gummy C-MD2s for slightly overstable when new to neutral power mid duties when seasoned a bit (possibly MD3 for slightly more overstable stuff if they turn out like that), a mix of S and C-FDs for low power shots needing a driver, 3rd run C-PDs (with a provision for some S-Lines as well) for workhorse driver duties, new and beat, S-TD or S-TD2 depending on whether you want a slow, gradual turn or a sharper one, P/S-DD2s and P/S-PD2s to taste. DD is also great if you want a bit straighter flight path for distance shots than the DD2 offers.
It's not an optimal bag, I would (and do) replace the putters with Ions and Anodes (almost all putting and putter driving), with a Basic JOKERi thrown in just in case (wind or a bit more fade required), replace the main max D disc with a Premium LEGENDa (just plain longer than any of my DD2s, and easier to throw), and I have a first run MVP Vector (short/slow overstable shots, and won't skip) and a first run Premium RESPECTi (silly overstable utility shots and thumbers). Other than that it's all C/D-MD2 (4 total, new and seasoned of each plastic), S/C-FD (two total, S is more understable), S/C-PD (2 total, S is more seasoned and better at line shaping), S-TD (two, a stiff for straight shots with only a little turn and little fade and a soft champystar for understable), P-DD2 (beat, tailwind and risky shots) and P-PD2 (headwind D, skip shots).
