While I'm sure any observer could make valid arguements for most weights being the most difficult, it appears 88 will be a tough " row to hoe " also. Some of the tough competitors we've seen so far Tyler Roth, M Dunn, Brake, Danny Floyd, Shavclk, Gahagan, Rempe, Lackey. No slackers in that list.Who knows which, if any, will move up or down in weight. Their are also a list of kids wrestling at 88 that are close to turning the corner and knocking one of these in an upset match.My vote would have to go 88.
