M_Boats: New Halyards and sheets

Montypals: Thinking of replacing my halyards and sheets. They are old, and starting to fray a bit. On my old Vagabond I replaced my halyards with New England Sta-set. Seemed fine. What do you recommend for the halyards and sheets? Also, diameters? Not sure by looking at the stuff. Daniel Rich M15 #208 "Kestrel" danielgrich@gmail.com
