Well it's the only one that had guitar in it, the other one was bass only if I remember right. Plus, I haven't checked but I think Rhythm is Marty Friedman, and Lead is Dave Mustaine, but I haven't confirmed that yet. The Lead Arrangement are the combinations of Marty's and Dave's solos Rhythm is full rhythm But this version has some issues and besides, i'm having issues with my LP Well I know that there are slight timing issues, but none that are unplayable. The section coming back into the main riff and Dave's solo for whatever reason never registers the hits. But like I said, it's the best one out there right now. Also.....very close match already. http://i.imgur.com/gzutu4G.png
