Yeah, if you can find Federal HST, I think that would be your best choice. Of the choices you list, I would put Hydrashoks at the bottom.
Clint Smith likes hardball.
Clint Smith may suggest using ball ammo, but on two different trips to Thunder Ranch in Texas, I watched him unload hollowpoint ammo from his 1911 before inserting a mag of ball ammo for his pistol demonstration. Smith also notes that properly hitting your target is more important than ammo choice in defensive calibers. This is a correct statement, of course, but he seems to be hedging his bets like most of the rest of us.
There really isn't any reason to worry about what Smith does or does not carry unless your particular skills, situations, and needs match those of his.
