Cal-Hypo's FINE since you CH level is 200ppm. Other than adding calcium it has the fewest side effects of powdered chlorine compounds. I don't use it much because I always have Liquid Chlorine around (Just really strong bleach--12.5%--but "Liquid Chlorine" sounds so pro...It actually works out to be the same as if I was paying $1.45/gallon of 6% bleach, so I use it. But it's the same stuff).

Using Dichlor or Tri-chlor tabs is only appropriate when you need to add stabilizer and your pH is fairly high, because both (especially Tri-chlor) drive pH down and both add lots of stabilizer.

The B-B-B method is really a philosophy of easy and sensible pool care. You can do EVERYTHING with Bleach, Borax, and Baking Soda, and just augment it with Muriatic Acid and CYA powder. You don't need ANYTHING else to run a clean sanitary pool, year after year. Oh: You DO need two more things: 1) Knowledge 2) a really good test kit.

Everything else is just for convenience.
