I’m absolutely not a Yngwie expert, but I’ve seen a lot of people swear he used HS2 and HS3s coil-split, over the years. But, again, I’m not an authority, only passing along what Ive read. And there’s always a lot of uncertainty around this stuff. But, I could have sworn I used to see this on Dimarzio’s page for the pickup, before he went to Duncan.
As far as the Areas - while the core design of a smaller dummy coil isn’t especially new, the Area series themselves are an iteration that can’t be much more than 10 or 15 years old now - I remember trying them shortly after they were introduced. I thought they balanced noiselessness with “sounds like a singlecoil” very well, especially compared to some of the earliest noiseless singlecoils I’d tried (the first gen Fender noiseless pickups were… not good, when I first tried them in the mid-90s, and my ear probably wasn’t even very good for this stuff back then since I’d on;y been playing a few years).
And yeah, some of the singlecoil sized dual-rail pickups get pretty damned hot. I tried a set of Choppers for a while, at some point along the way - probably sounded more like a singlecoil than a PAF, but only just… and they were awfully hot. Not what I was looking for for that guitar, but definitely a fun pickup.
