Yeah, it's definitely 10:1 and 13:1 system. :-P

The funny thing is: some people told me that the "8:1" cascaded systems are easier to sheet than the 8:1 conventional systems. Well, of course they are, since they are actually 9:1.

When I floated this same design some time ago on catsailor, I was told that cascades had fallen out of favor, as too unreliable, having limitted travel, and requiring lots of line. Has this changed due to the stiffer carbon mast? Have the downhauls also changed? On my old T, I kinda like my 7:1 downwind. I can't imagine what 13:1 would be like!

At Nationals last year, I did notice John and Charlie with a 8:1 + untapered salsa line + carbon mast on their boat. But as I get older, I do start dreaming about 13:1.
