For your classically 'liquid solo neck' tone, I guess you're looking at something like the Cold Sweat (or even Abraxas). For the bridge, I'm not entirely sure what to recommend. Miracle Men are likely to be too harsh for your axe, and the cleans aren't quite up to the other pickups, so in that sense, the Holy Diver makes sense, especially in alder. The Painkiller might also be too much - both the PK and the MM are BRUTALLY articulate pickups, which is great for thrash. The MM has a HUGE but tight bottom end, but also quite prominent highs and high mids (to my ears).
You *might* be better off with an AlNiCo pickup for the bridge to make sure you have the really sparkly beautiful cleans also...
The very best thing to do is to telephone Tim (number on the BKP website!), and ask him - he's always spot on with his recommendations - the man knows what he's talking about!!
