The even weight classes drive me nuts. Tied dual meet criteria should just be who won more matches, IMO.
Where would you add a weight class if you could? Would it shift around the other classes?
I would like to see something like 125, 133v132, 141v140, 149v147, 157v154, 162, 165^168, 174^177, 184^190, 197^210, 285^275. This lines up a little better with the international weights. Otherwise, I'd like to see one get dropped in between 25 and 57 and push 25 down. This is one of the few sports that little guys can be on even ground and I'd like to concede that, even though I never wrestled under 160.
