The blocks which makeup the hardware for my traveler have become a victim of age. I'm in the process of replacing the fiddles and line. What size line is recommended for 22' hunter with 220 square feet of sail. I'm getting getting conflicting recommendations depending on who I ask; anything from 1/4" to 1/2". I want to be sure I have a system as robust as needed but I'm not in the habit of over-doing something figuring bigger is better.Can't seem to find the original specs so I'll seek some advice (again) from the form.Thanks
