I know it is best for me to find my own spots, but at the 12-20 bracket I'm having quite the time trying to find a consistant spot to trust leaving glider on. Last night I left it running to wake up three times with me dead. Really didn't get me very far at all. Is there anywhere anyone recommends gliding for each bracket? I'll work on finding my own, any tips besides the ones glider offers are welcome also.
