I've found the 50RIA* work fine. They're fairly cheap too, I bought a new 50RIA120 for 20 dollars.

you only need to look at the pulse ratings, the 50RIA120 can take 1.5kA for 8.3ms IIRC.
some of the semikron bricks can take upwards of 5kA pulsed. I've been using my SKKT132/12E to switch a 1.3kJ bank with great success.
