56F game temp today. 8 year old DD (10 year old size) wants to use her new 30/19 LXT in her game today. She was hitting bombs yesterday with it but it was in the mid 80s. Should I let her use or make her use her 29/18 one more time? I think the chances of her breaking it or pretty slim, but can cold weather take the pop out of a bat permanently? I realize they don't perform as well in colder weather.
