Shortgrass, we helped a neighbor freeze brand his heifers one year and he wanted to use some steel irons that he had so we tried, none of them worked. The steel is not thick enough to hold the cold long enough to freeze good enough. Lucky for him, we put the numbers on with my brass irons, only the letters were the iron so at least the numbers turned out
As far as doing them when you are synching, just make sure that you have enough time to get everything done, freeze branding is best done with a "don't hurry up and get it done" attitude, take your time and do it right and they will turn out.
