Barry,

I've never objected to those people who refer to "duel" competitions; however, I still believe that "dual" is the correct terminology, if for no other reason than it is the proper wording in the National Federation of State High School Associations rulesbook. I believe that the appropriate reference in the dictionary is with the use of dual for numerical purposes, where it represents two (as in two teams).

Regardless, there is no chance that anyone would misunderstand either usage where it pertains to wrestling.
