My money's on Blofeld to win this one hands down, but Boycott might run him close.
Personally I'll happily listen to most of them apart from Blofeld and Boycott, although Tuffers can be quite juvenile and doesn't add much insight. I think Ebony Rainford-Brent has been a really good addition - I do like listening to her, especially her understanding and enthusiasm for the women's game.
Perhaps I should have had two separate polls, one for summarisers and one for ball-by-ball commentators, but I've lumped them together.
