DEFINITELY. The funny thing is, I think you have 30 or 33 Ohm resistors in yours. haha. I'm not sure though. The main reason I want to drop the gate resistor size is the new mosfets have like 2 times the gate charge as the ones we're using now. I wonder what the voltage spikes would be for 10Ohm, 1000amp. I guess double the current, double the spike, and cut in half the gate resistance double the spike? So maybe the spikes would be 4 times as bad as now? But the gate charge is bigger so maybe the turn on time would be about the same, so maybe we'd only have to worry about the 1000amp?
