For worked out solos, those are pretty bad. I think Fade To Black was pretty overrated, and I won't comment on the 'originality' of the Master of Puppets bit.
Mine was pretty much off the cuff - I cut out a section in the middle because the string popped out of tune, yes, but it's two takes where the second take is a replaying of the first one. It does, honestly, help when you have more 'modular' solos with breathing space between phrases, so then you can retune your guitar and few people will tell the difference. Gaah, I should just stop changing strings.
