When you say a Mahogany Soloist, is it a Maple Neck Thru? As that can make all the difference. It will be brighter, but also have a better Bass transfer.
If it is a maple Neck Thru, a Nailbomb (Ceramic) may be too bright, although the mahogany may tame it. A Miracle Man serves very well (although the treble rating seems high, it seems to sound actually quite good in bright guitars), but if you want something less tame, maybe try the Aftermath, although it is quite dry and requires you to adjust your picking technique to preciseness as it tracks really accurate.
If it's a Mahogany Neck Thru, then I say C-Bomb all the way. It's an awesome pickup.
For neck, I beg you to get a Cold Sweat. It's greattttttt, as Tony would say :P
