I really like the Blackdog, the tonal character of the BD a Hot PAF, with more midrange growl. It's going to be open like a PAF, so it will not have that full modern feel. If you want more modern, you can't go wrong with the Polymath. It's great, very similar tonal characteristics to the BD, good mid growl, with lots of open harmonics. Bolt on maple neck on Alder also lends itself to the Holy Diver, which is a pickup I hated in a Mahogany/Maple bolt on PRS and also hated in my Ash/Maple Suhr, but LOVE it in my Charvel (Basswood/Maple Guthrie Govan). I don't have experience with the Supermassive P90, but I do have a Mississippi Queen HSP90 in the Neck of my PRS and it is wonderful. Always thought of putting a supermassive in the bridge of that guitar, but the Abraxas that's in it now is just too good.
Good luck with your search and let us know which direction you go.
