Thanks for the feedback. I also started out with the impression that P90s weren't as "good" as humbuckers or tele/strat style single coils. But after more experience with them on my G&L I have fallen in love. I have a pair of Supermassives and after some getting used to them with my pedals and amp, really dig them.
I am probably going to save up for a Collings 290dc and those come stock with the Lollar P90s with alnico poles. So it may be quite some time before I purchase it (it's roughly $3k, which will take me a while...) I can actually do a side by side if I get that one. Since it's a 24 7/8 scale with Mahogany body and glued mahogany neck, it's probably quite warm sounding. My guess is that those Lollars compliment that guitar nicely because they may have a bit more clarity than a standard P90 to balance the warmer tones from the neck and body.
In the meantime, I'm doing a build and not sure if I should use the Piledriver bridge and Abraxis neck set, or if I should rout it for P90s instead. If so, I'm hoping someone has used those Lollars and can comment on them. It's hard to imagine the Nantucket isn't awesome but I am hoping for some info on the Lollars and what character they have.
