Can't help with the soundclips I'm afraid, but I have had an alnico Warpig set for almost 2 years now. I've used them in two different guitars - a thru-neck ESP (maple neck/body core, mahogany wings, rosewood board, Floyd Rose) and a custom bolt-on Warmoth (mahogany/koa body, maple neck, ebony board, Wilkinson).
I really do think the Warpigs will do everything you want. They are great metal pickups, with as much low end as you could ever want, but they are also far from being one-trick-ponies. They clean up really nicely, sound good for classic rock stuff if you back off the gain on the amp, and they coil tap very well (another upside of so much output I guess).
