Nothing has gotten the shields down on my Python with G5 reinforced shields with 2x G5 heavy duty + 1x thermal resistant booster since I rolled it about a year ago(? I guess.)
For a mission-running Python, it just doesn't matter how you engineer your shields, in my opinion - the buffs you get will make it basically invulnerable. If you want to bounty-hunt and engage FAS wings or whatever, then yeah, grind those mats and roll-and-reroll-and-reroll those biweaves.
For PvE, all the numbers flying around are willy-waving, nothing more.
How do you guys with four shield boosters use SCB?
They absolutely m fry your ship. I hit two 6A without a sink, and everything started to malfunction.
Not a criticism gents, just trying to learn something.
Boost boost boost, turn off lots of modules, fire
one SCB. You'll probably hit 120% for like 3 seconds. Wait till you cool down. Do it again. If you turn the thrusters off, you might not even hit 100%.
