The OneFC has a much better weight cutting system and i still expect UFC and another organization will adopt them. From what i remember the OneFC checks the weight of the fighters in check well before the weigh ins as they should be around that weight limit even during off season and the weigh cut some of the fighters go through in the UFC is brutal.
I also hope that UFC will use same methods of weighing-in fighters. Their weight cuts I count as cheating. If you are heavy, they go to other division. There is no need to cut 5-15kg before for weight-in and go blackout, and then gain them back or more before fight. This is not normal. This is not fair. That is one of the reasons they get injuries, where there should not be.
Well, I see where you are coming from. Losing weight very short period of time and gaining them back again is very harsh on the body and has bad consequences. I'm impressed by the method used by OneFC. I did not know about it before. This method seems fairer to me compared to the one UFC uses. Hope this gets implemented all over the fighting scene.
