One - Mr. Stanley is right. The reason they did away w/ the Saturday morning weigh-in is that hardly anyone used it. If there had been a demand then they would have keep it.
Second - Regarding the short length of time for weigh in. The State tournament is fairly long compared to most National Tournaments. USA Folkstyle tournament - weigh in period 2 hours. Southern Plains and FS/GR Nationals - weigh in period 20 minutes. The trend is towards having all wreslters together at the start of weigh in so that everyone is weighed in at the same time. With the emphasis on controlling weight cutting you are going to see shorter weigh in periods and weigh ins closer to wrestling time.
