After Black Album maybe, but there's some pretty good goddamn solos in the 80's albums. And I don't even generally like Kirk Hammet's style or solos in general. I can't remember too much of Kill 'Em All's solos. I think they were pretty much just wankery, but the three great ones have pretty good ones. My favourites :
Ride the Lightning
Creeping Death
Call of Ktulu
Master of Puppets
Sanitarium(the third one is meh, the others are quite possibly my all time favourite Kirk solos)
Disposable Heroes
Blackened
...and Justice for All
