If a Cutter has that much Shields, it either has barely or even negative resistance to Thermal, or no heatsink. If he uses a SCB and has no Thermal Vent weapon, he is roasting himself heavily. Even if he has a thermal Vent weapon, he has to hit with it 99,5% of all Cutters use Gimbals for a Reason, and those are not reliable on a range beyond about 3 kilometers, in my experience even less, because of their build in wobblyness.I can see where OP is coming from...
It is daunting facing 10,000 HP of shields (Not to mention time consuming! lol)
