Powders and temerature tolerance.

[Wild Bill G]

I have been reading a lot about temperature tolerant powders. What powders have you guys here found to be the most tolerant and least tolerant. Are there powders that have been around fore ever that are just as good as the new ones or is there a world of difference.
