almost any build is viable in single pass, if it is not based around a specific item, like a wolfbarb or a fuzzydodger. its just a matter of patience, which i tend to not have. also it depends on the player setting in hell u are aiming for.
for barbs: berserk barbs are very good. nightfish wrote a guide about it. i´ve taken a frenzy to a5 hell on p4, where i ripped him in the frozen river, but not to souls
for a sin, i´d probably try a blade fury sin, theoretically still a trapper...
Assassin- probably a kick/trap hybrid build, pure kickers require decent equipment and pure trappers can have problems with lightning immunes, although death sentry does an ok job.
Druid- Wind Druid, there's really no other option. Not hard to make and only really has problems with Physical Immunes, but hurricane still works on them, its just slow.
Pally- Hammerdin. Very safe due to high resists and blocking, and plenty of damage with very few immunities to deal with.
Barb- If you have no practive this could be hard, but I would use Berserk. Lots of damage even without great equipment, the downside is the loss of all defense. With max block and Battle orders you should be fine, just get used to using Howl to get out of tricky spots.
