31Dn was the last one I figured out - it's really contrived.
EVER(Y) = almost the best possible (see Chambers)
TEAM minus AE (aged) reversed = TM
Omit M and there you go!
I didn't particularly enjoy this crossword. I've only been doing these crosswords a short while but I am getting a bit tired of another crossword with......the wordplay indicates an extra letter not entered in the grid..... Surely someone can invent something a bit more original. Thanks to all for the hints along the way - I would never have got to the end of this one without the help.
