Having been through the Y10 parent wringer, they should 100% drop it. I'd probably keep Y12, but no championship, RYCs and SYCs, maybe a NAC. I'd also change the age breaks for Y12/14 to February to match Cadet and Junior. But they'll never scrap y10 - why give up the revenue when parents just view it part of the cost of getting into Harvard? And while some flavor of RYC/SYC is probably still economically viable without Y10, it'd be much harder to host without Y12 as well. I guess we'd end up with a RJCY14C series replacing SYCs and RJCCs. The revenue thing also probably applies to coaches and clubs as well. You can charge people more sooner by pushing the nationally competitive age lower.
