Puzzles #641, #642 & #643 - Almost Symmetric (Masyu)

About 3 months ago at this point, I got a bit obsessed with trying to make a non-trivial Masyu that was almost symmetric in its clue layout, but didn't solve symmetrically. The second puzzle I made was a small one based on a simple yet somewhat advanced idea.

Another interpretation of the theme would be to have a symmetric clue layout with only a minor "blemish" from being fully symmetric. My third attempt - still posting out of order - ended up with two such pearls and a fill that got a little bit insane in the end.

Ultimately though, I think my first attempt at this theme was the best. Definitely the hardest break-in of the three, and though the later stages are easier than the prior puzzle that's not really saying much.

Thus concludes my backlog of unposted puzzles. With any luck, I'll have more queued and ready to go by the time you're reading this, but no promises!
