But if it's really bad metallurgy/quality then it might be wise to change to an aftermarket spring that has a better quality and reliability reputation. That's what I think most people are trying to determine.

I do have an aftermarked MTI (Houston) C2 cam .576/.576 224/224 112 LSA. Gotta pay to play; Good luck finding your replacement springs. For your purposes, I think I would stick to the yellow LS2 springs.

I have heard the same, and with a ramp up in production one would assume that the failure issue has hopefully been resolved and possibly the reasons were addressed through metalurgy or possibly a new vendor. Assuming that the LS2 is also running the same springs, you could check the C6 section for problems as well as the GTO forums. I haven't seen many lately though.
