I agree with Phil re 19a (Fumbling would have been a better choice of word) and with Brendan - it only really equates if you use it in the past tense. Not the best clue.
I'm with Loubylou on 7 down - I also didn't know this, and having got it, can't parse it. I can see the anagram of rain, but how does the rest of it work?
Apart from those two, I really enjoyed it, and found it on the easy side. Two rhyming pairs this week! Lots of great clues but favourites were probably the rhyming pair of 11 and 20.
