CDE 942 capacitors are specially designed for massive current pulse discharge operation. I personally use the .68 uF 1600VDC rated CDE 942s... wow are they great!

I've found those yellow GE caps everyone hates are actually fine, at least for SGTC's, as long as you have multiple strings. Single strings pop like popcorn though. My NST coil has yet to blow two parallel strings.

The capacitors look like these so I don't think that they are suitable for TC use.
Don't be so sure. I have about a hundred or so PP caps just like that. The ratings are a bit different, 1000V @ 0.22uF, and I used a string of 45 or so of those for my SGTC for several years for long runs with no problems.

I just learned how to embed the image in my post so if I did something wrong tell me and I'll fix it ASAP!
