Not even a size 6PD can deal with a size 7 Bi-weave unless you use SYS focused on PD and LowPower/LowDraw on shields. Using a size 7 Biweave can be dangerous since you will have your sys cap empty for a long time, not being able to use other sys dependent stuff for quite a while.
But why would you put a Bi-weave on a ship that's not supposed to engage often in combat?
A-rated or Primatics will be the norm for dangerous routes/open and most probably NOT size 7, even tho the size 5 PP G5 Armored can easily deal with a size 7 Prismatics
Nope.
That’s not true. The rule of thumb for shield experimentals vs PD class and Shield class for Thermal Resist Biweaves is:
- If PD > Shield, go Fast Charge. It can handle biweave SYS draw in its sleep. I.e. a Corvette.
- If PD = Shield, it’s a judgement call. If your weapons are numerous and/or require a lot of WEP, or you don’t want to constantly have 3+ pips in SYS, or you need the 20% power savings to make you build fit its power plant, then go Lo Draw. Otherwise, if 3 or 4 SYS pips are always available, your weapons are few and/or notably low WEP draw, or you have tons of power headway, you can use Fast Charge.
- If PD < Shield by one class, then Lo Draw will keep SYS afloat well enough to be practical. Fast Charge will bottom you out.
- If PD < Shield by more than one class, then your SYS capacitor will be having a stroke either way, so you’re probably better off with a Prismatic shield so SYS draw is no longer an issue.
For Reinforced biweaves the same rules apply, but it’s shifted 12% towards Lo Draw thanks to the increased distributor draw from that primary engineering.
Honestly, Lo Draw is one of those criminally underrated experimentals for all types of shields. 20% less power usage, so you can fit better stuff on your ship. 20% less SYS draw, so you don’t have to babysit SYS unless you need the damage resistance, so you can concentrate more on boosting and shooting. The loss of optimal multiplier seems to hurt, but that also means your recovery time is lower because it now has a lower MJ target before the shields snap on. The regen bonus from Fast Charge only really becomes notable at class 6 and above, and even then it’s not make or break.
