Are you buying all nerw blocks and line or trying to match new line to existing 3/4" blocks ? I use 3/8" halyards, it's stronger than needed but easier to hold than smaller line, & a pretty good compromise on the cost/comfort relationship. My recommendation would be 5/16" or 3/8" line.

What I have at 3/4" and blocks to match seem large. Please advise.
