[Crawl] Where next?

[ I am at a loss.  The Vaults?  Back to the Abyss? ]
After many ( oh so many ) character deaths, I am playing
a moderately successful Troll Fighter.  I have cleared
down to D:20.  Cleared the Orcs, the Elves ( nasty elves ),
The Lair, The Hive, The Snakes ( my first rune ever ), and
had a very exciting trip to The Abyss.  The power of the
monsters in the Main Dungeon is beginning to outstrip the
abilitites of the Troll.  

So, I figured I will head to The Swamp.  I hate Hydras.
One on one I eat Hydras for lunch.  I just ran into two and
had to flee after killing one.  Okawaru came through and kept
me alive at 5hp or less for many rounds.  Keep in mind I have
never, before now, seen anything other than the Mines and the
Elven Halls.  Having read this group for awhile I am kind of
spoiled already though. [ Darshan and Loonie at least have
mentioned the amazing thing that is confusing touch. ]
