Thanks for finding these things and thanks for posting the link.
From the picture they look like what I purchased from Redhead Sails. They were nylon, they worked just fine
I requested some information on the dimensions. If it's even close to what I need I am going to buy 100-200. My Tornado uses 16 and my F14 uses 28.
Every time I find a deal like this I buy enough to last a couple of years and I have never regretted it.
