Still working on a CL5 size yacht, and I'm going to have to make a decision on the pulleys soon.

Seems like there are 2 basic choices: multiple in-line single pulleys, or a single pulley with multiple rollers (sorry, i don't know the jargon...).

Does either setup have a benefit? Or is it just whatever i can get? Or whatever fits?

Would like to get it right the first time, since the pulleys are expensive here.....

Thanks, John
