I'm finding that I am happier when my decision is based less on "weak shields=biweave", "big shields=standard/prismatic" and make the decision based on how I'm playing and which suits it better. For instance, biweaves work much better for me in RES sites, the travel time and often negligible damage I take from single target enemies keeps my shields topped up and they are strong enough to let me survive a tough wing (2 Clipper and an Anaconda) without breaking, maybe using 1 SCB charge, this has allowed me to pack far fewer SCBs, keeping my ship lighter, faster, more maneuverable, things I prize in the many 1-3v1s and travel between fights in a RES

For combat zones though, I find myself taking less big bursts of damage with time in between and more steady damage with occasional big burst. Maneuverability and speed are less important in the CZ because the enemies are usually occupied at least partially by allies and the enemies are all much closer (no travel time, no need for fancy maneuvers), so I pack a stronger shield with more SCBs, it lets me survive the big bursts of damage from bad positioning, which I find more necessary than passive recharge and then I occasionally pop an SCB when my shield just get whittled down from constant fire. The biweaves don't hold up enough under the occasional heavy fire to work for me in a CZ.

I do tend to run just biweave in my faster, armored ships though, their strength is hit and run, so they get enough reprieve from damage that the recharge comes into play big time. Took on a wing of 3 dropships in my FAS and the biweaves were magnificent. Lost my shields twice during the fight, but they came back twice, my hull easily shrugged off the heavy fire until I could get some distance and come back in again with full shields.

As a trade setup, I'd just go with D rated shields, I get the strength of the biweave and good jump range, the shield is more than enough to tank fire with 4 pips and chaff while I high wake away and they'll top up at the next stop.

Each pilot will have to find what works well in which ships, which is heavily dependent on play style and the environment you're in.
