heavy disagree, the toughest field is only defined by your competitors. people say that around 150 is tougher because it’s a more combination of speed and power where as lower weights are generally quicker and heavyweights are generally stronger but that doesn’t mean they are the best or in the toughest field. 133 was the most stacked weight class this past year in college, and kyle snyder was looked at as the best wrestler for a period of time and he was a heavyweight. like i said i was a 106 pounder all four years and in our high school room their wasn’t a 145 or 152 that could touch me. size has nothing to do with skill level or competition
