I have a 2003 allied composites mast with a 2007 Glaser sail. I sail at 190 lbs. I am still getting dialed in with my mast settings, but my current settings are 34 on the old loos gauge and 63mm of spreader rake.

If you are getting into the range where you are worried about the mast breaking from diamond tension you are well beyond any setting that would be fast. The tightest I have seen anybody run the diamonds are 36-37. Small changes make a big difference on these boats.
