After having cold solved 3/4 of the clues with none entered I was toying with the idea of calling it a day. My usual ploy in alphabeticals, of picking one answer, in this case one of the 3 letter ones, and putting it in all available 3 letter spaces then trying to build around it has always served me well in the past but in this puzzle,, due to the double letter cells, it isn't working. However, after reading the largely positive reviews, I've been encouraged to carry on:-)
