G6 cartomizers safe with "tank-cracking" juices?

[HeadInClouds]

I apologize if this has been asked and answered before, but I can't find the info...

I know some e-juice like red-hot cinnamon and citrus can mess up G6 mini-tanks by reacting with the plastic.
Are these juices safe in Halo's prefilled or blank cartomizers? My G6 starter kit cartomizers are metal, but is this a "safe" metal?

If the cartomizers also can't handle these juices, does anyone know of a Pyrex one that can be used with the G6, or would that require extra adapters/parts and a degree in e-cig engineering?

i use tank cracking juices in my g6 cartos.

You can use all juices in G6 cartos. Cracking only became an issue when the plastic tanks came out.

Thank you both for the confirmation. The juices are already in the mail to me. Good to know I can try them out without hunting down new hardware right away!
