In Mist she was Standing solo..

oh cool, coz when I tried learning it, I hated doing it as a chord/arpeggio because when you hit all 4 strings it just has that ugly disharmonic sound, and I don't think Peter actually did that on the recording. Doing it with single fingers though is a real bitch.
 
I play in flames in standard tuning too, it sounds weird, but I don't have to go through the hassle of tuning. And I've always rolled my fingers in the Mist solo, it's just like any other sweep, you can't let the notes ring out or it'll sound like shit.
