H77,
I have the fiddle blocks for an adjustable setup but I removed them after I almost went for a swim while singlehanding <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" /> (Thank God for stop knots). I also heard a story of a sailor who almost lost their thumb when it got caught in the block during an emergency maneuver. I think it was one of HobieGary's friends. I know there was a story written about it on TheBeachcats.com, but I couldn't find it.
