What a different dimension of dough whisk tells you? Thank you.

Are you asking about Danish dough whisks, which are different from balloon whisks, and are designed especially for dough (as opposed to batters, eggs, etc.)? I have a dough whisk, and find it quite handy. What in particular are you concerned about? ;o)
