Fine effort at a list, but there clearly remains scope for further honing when, for example, the one-and-not-even-any-good-move-wonder of Reiver's Logic appears for Lednock while the puzzling, aesthetic delight of Afraid of the Wave remains on the bench.
Pushme Poolewe is too good to be absent. Spanking the Monkey is excellent but belongs to a list of 6th grade problems - we've all climbed harder 5A slabs in Font - but Monkey Spanking is good enough, and just about hard enough, to replace it. Meanwhile Slap Happy does not belong on any list at all, but should be stored inside, shame-facedly, next to ones first botched attempt at a campus board.
I don't expect anyone to agree with me though!
