There is athletic commission that do same day weigh ins. I believe Alabama is one of them. So there has been the application of it to draw conclusions from. I personally do not know how it is has gone but my instinct is it less safe. If a fighter goes into weigh in heavy he is going to have a rough cut but he will still be able to rehydrate. If he has to be less than ten pounds going into the fight he will not be properly hydrated come fight time and have to take blows to the head in that state. That is worse for you than a big weight cut.
A big reason why fans don't like weight cutting is seeing large weight advantages come fight time. Banning weight cutting and having fighters fight at their natural weight helps reduce that, but it will still be rampant in this sport given the few weight classes. As long as you have twenty pounds difference between MW and LHW you are going to have fights where the fighters have close to that in weight discrepancy. A fighter that is just big enough to fight at LHW is going to have a huge weight advantage over a fighter that is a little bit too big to cut down the MW. The entire division system needs to be restructured and have more division infused into it. 155, 165, 175, 190, 205, 220, 265 is perfect IMO.
