My personal Johan Reinholdz boner stems more from Inner Circle and Going Under off of Chimera. Going Under...right at about 2:45 into the song. AHHHHHH so good. I just acquired their 2008 release but haven't had a chance to listen to it - I really hope it rules as much as Chimera because it's a gem of an album.
I think my vote for favorite Swedish guitarist actually goes to Kristian Niemann. What a SERIOUS dude. I try not to die from envy every time I listen to some of the solos from Demonoid and Therion.
