Main sail sheet

As per your guidance, I bought a SCHAEFER 7 SERIES 2250# SWL SNAP SHACKLES MAIN SHEET, VANG 4:1 80' NEW 1/2"LINE, I speced the line as per details I found to ensure.

I am going to attach at the end of the mainsail boom, and then to a pad eye. I was thinking a Wichard 607639 they are rated at 14110 working load.

Sound right? Harken shows crazy load rating for 30 knots based on a non-reefed mainsail, in this range?

Thanks all, will send photos of the traveller install.
