I am using some 600v 600amp chassis mount IGBTs that can handle like 2400 amps for a very short period, with a film cap that can handle short bursts of 10,000 amps. So, 6 x 11 amps (continuous is around 11 amps) is still safe. If I wasn't doing such brute force with big fat IGBTs, I would definitely do the resistor soft start.
