I know we all hate vest that gives us the weird tan lines. But I always wear one unless the wind is 5 or less. I have had two experiences where they where life savers. Once I was hit in the head by by the boom on an unplanned jibe and the other the trap line broke while on the wire and got dumped. There will be that weird time when you are not always holding on to the mainsheet. I would rather be uncomfortable than have to tread water for a long time.
