I'm very, truly sorry for any spoilers but starting with xxxxx isn't the worst. 4. Should have been 3.
Lost 4-5, when the obvious word is staring you in the face and you ignore it you end up with a poor score, should have been a 3.
My usual starter gave me one juicy, then I wrongly took notice of Drum above and tapped in for a birdie three . . . . it was a spoiler and it did spoil it. I've now edited your clue, Drum
