Which SB mods you use will depend on the shield mod (thermal vs reinforced), which will depend on personal preference, or math, whichever you favour.
I'm currently running 5x HD and 1x Resist with a thermal biweave on my Corvette, simply because I'd passively farmed up a tonne of mats, and was able to roll ~54% bonus, plus ~4% resistance on the first 4 HDs, so didn't need 2 resistance mods to get to the 50% mark.
As mentioned, for the smaller ships you may run into power issues using A Class SBs, but an overcharge PP may solve that, depending on how much heat you can get away with.
Personally, I say do the math. Mock up your ship in Shipyard/Coriolis with thermal vs reinforced shields, then add some HDs vs Resist SBs and see which is stronger/your preference.
