There is a running and continually being updated list here on ECF of flavors known to have cracked or melted tanks. You can find the link to that thread in my blog which is here:

There are a few ECBlend flavors known to crack tanks, but none of those which you asked about. You should be safe to use those. You should bookmark that thread or my blog article for future reference (I try to keep the latest list updated on my blog).
And BTW, welcome to ECF! We're happy that you are here. Feel free to browse the forums. Once you have successfully completed 5 posts (and the server resets, approx every hour), you will be able to post on any of the forums here.
Also, I'd like to invite you to sign up as a member of CASAA, the advocate group which will represent us vapors' interests in the upcoming FDA redeeming regulation. It's free, and only takes a minute. The link to join is at the bottom of my post.
