Figuring out the hardest levels in CCLP3

[Ihavenoname248]

Here's the order I would rate these for difficulty:
10. Yet Another Yet Another Puzzle (140)
9. Rotation (139) with these three all being pretty close, for different reasons. The hint here explains the mechanism well enough.
8. Mr. McCallahan Presents (149) though this could be seen as easier than the ones above. If I remember right, the ball pattern in the bottom left is impossible to pass through in its initial state, though I haven't checked the level.
7. We'll Be Right Back (134)
6. Recurring Dream (145)
(large spike)
5. Same Game (143)
4. Avalanche (147) I got these two pretty quick- they could be easy or hard depending on what you find.
(another large spike)
3. Suspended Animation (146)
2. Vulcan (137)
(yet another large spike)
1. You Can't Teach an Old Frog New Tricks (144)
