Original Trembucker vs. Dragon 2 vs. Air Norton

[Kel]

I'm still looking for the right bridge 'bucker for my alder PRS (into Marshall Super Lead). I'm looking for medium output with some thickness in the mids, and each of these pickups seems to fit the bill according to their descriptions. I'm leaning towards the Dragon since it would seem to match the guitar, but they're relatively expensive. Are they worth the extra $$? The PATB-1 is intriguing as well, but seems hard to find. I don't mind the looks of them like some people do. Air Norton has the best description and seems close, but I haven't been thrilled with most DiMarzio's I've played.

Anyone have some experience with these 3? What are the differences?
