Need advice on panning. Short intro w/6 tracks of guitar

Need some mixing help on this intro. Got quadtracked guitars panned L100 L80, R100 R80. Have bass staight down the guts, drums L/R 100. Now I have a little harmony going on and thats down the guts to. Also have a little 8 note riff happening half way through and that is also panned down the guts. Am I panning shit right? Or do I offset the 2 single guitars. What would your choice be? This is a raw mix, no processing except the bass.

9.5mb file.
Thanks in advance.

I would put the guitars with harmonies like 50L/50R or when are one harmony running she will be on center but when enters the second harmony you could pan the guitars like 50R/50L with automation.
 
I usually don't pan drums 100/100, I do 80/80 so it allows guitars to have a little bit of their own real estate in the stereo field. This especially helps me when I have a lot of stuff going on in the mix. If you have a drum bus setup for verb it would still fill out the whole stereo field but I rarely do this.
