High gear or low gear

Sorry about new thread I couldn’t find anything in topics. I’m new to polaris. I have a 2016 sportsman 570sp. My question is this. I live in wv. My normal trail riding is mostly hills with an average speed of 15-20mph. I run in high. Should I be running in low? I’ve heard that if I run in high it would mess the belt up? Any pointers would be appreciated.
