Favourite opeth riff?

The first riff in The Funeral Portrait just after the acoustic opening is the sex
 
Here we go...

1. The first lead in Bleak, when the song kicks into gear (starts at :20).
2. Deliverance outro (I may love the drumming more than I love the riff itself).
3. The funk portion in The Lotus Eater.
4. The little acoustic bit in Heir Apparent (starts at 3:55)
5. The Baying of the Hounds intro/verse riff AND the really dissonant harmony they play right before the first mellow bit (3:04-3:15)

and finally

6. Every riff in The Drapery Falls. Goooood shit.
