how much diamond tension should be "dialed-in" on a boat with a spin (e.g. what should my diamond tension be with a spin on a traditionally non-spin boat?)
I'd guess at least 400 lbs. Do you run prebend on your mast? If so, you should have a fair amount of diamond tension already. On the Tiger we ran 900lb with the old square top. I have heard of an I-20 sailor running even more.
