There's a lot to be said for expectations. Ensign Timmy in the HTs can ask his HSC IP, "Show me cool HSC stuff!" and the syllabus already has low levels, LZs/UPLs/whatever the kids call it these days, etc. ENS Timmy says "Show me cool Romeo stuff!" - you're not gonna tune up the TH-57's sweet radar/ESM/ASW suite. Right or wrong a lot of HSC nuggets show up to the Fleet with these expectations. HSM signed up for nerd shit and knows it. Happiness = Reality - Expectations.
Within the "high end fight" that's the all the rage these days, HSC doesn't bring a lot to the table. Sure, LOG/SAR, AR of opportunity, absolutely. But you don't need a squadron full of Block III's and PR/SOF level IV's to do that.
In fairness, as I've said before, from my view as an HT IP, I anecdotally believe that R's are the preferred platform of most graduting wingers nowadays from the HTs.
