I've had some help with this question, but getting near purchase time and want to make sure I have a right answer.On my 290, the spinnaker blocks attach to the arch and lead the sheets back to the winches. However, always leading the sheets to the winches seems overkill. I'd like to purchase blocks with cams and at least be abe to secure the sheets at the arch on lighter wind days.I know the sheets may need to be released quckly if a problem occurs; the cams allow that. I'm a little concerned that the cams might not handle a heavy load from a spinnaker, so I recognize that this idea is really only for lighter air days.Anyone see a problem that I'm missing with using blocks with cams? Anyone actually do it this way? Searched the archives and the lack of anything even remotely related says I'm barking up the wrong tree. Always appreciate the education.Paul
