M_Boats: jib sheet diameter, material, and construction

I need to add a missing jib sheet. The existing one looks to be 7/16" diameter. Casey (This Old Boat) recommends polyester double braid for sheets ("Period."). A sail-rite document ( https://www.sailrite.com/PDF/Rope%20Selection%20Recommendations.pdf) has a table of recommended diameters, and it looks like 5/16" would work for my M17. Does that sound reasonable? Thanks, Rob First Time Sailboat Owner
