I want to get as close as possible to a 498T without the mud!

I think Crawler, especially if you can work a deal for that used set.

I have a Crawler in a swampash-strat, maple neck, ebony fretboard. It's brilliant in there, warm, fat, with a round but not dull topend (there is enough treble). The splitted sound is very good too.
The Crawler is designed to work equally good in strats and LP's. I don't have experience with the Crawler in a mahohagny setneckguitars. The Crawler is tight enough for most styles in my strat, but the lowend coul be a tad too soft in a LP. I always turn the bass on the amp a bit down to reach the sweet spot in the lower register of my guitar.

I own both the Crawler and the Abraxas bridge pickups, and for your specific situation I recommend the Crawler. It's midrange has a center midrange focus that makes it sound very fat and warm. The Abraxas is also a fat sounding pickup but has less of the center midrange (still enough midrange though) and more highs. It sounds quite similar to the Holydiver bridge but a bit more open, i.e. it has a bit less output.
