I have an '87 Jackson strat and agree it's one of the siky-smoothest necks I've ever played. Mine is set up as S/S/S with Bardens, so it's my actual strat, just with a pointy headstock and a original Floyd. They may not be cheap, but they're much cheaper than the earlier San Dimas era Charvels and play/feel very similar.
Love the soloist. They're great guitars. I've played a ton of them over the years (as well as Kelly's and Warriors's) but never owned one. I prefer the unfinished bolt-on necks to the painted ones, but still neck necks - one of the warriors came from the factory with an unfinished neck, and it was sweet.
