My Bristol 45.5 does not have tackles to tighten up the runners -rather a tail is taken through a turning block to a winch. The lead for this is not as fair as it might be and it takes up a winch, so I am thinking about changing to tackles for this. I was wondering what strength of blocks would be needed to make up a more conventional tackle (4:1?). I would use a low stretch line of some sort, should I go to something fairly high-tech or stick to a high-end dacron?

Thanks for any suggestions.
