VOTE: What's your pick for the best attacking duo in MLS?

There's nothing quite like a one-two punch up front.

From D.C. United's dominant Marco Etcheverry-Jaime Moreno axis of the league's early years to the David Beckham-Landon Donovan pairing that won two MLS Cups and two Supporters' Shields for the LA Galaxy, dynamic duos have often prospered in MLS.

Now Susannah Collins and the rest of the MLSsoccer staff are wondering: who is the best attacking pair in the league today?

LA have the star combo of Robbie Keane and Giovani dos Santos. Orlando are paced by the push-pull force of Canadian target man Cyle Larin and playmaker Kaká. The New York Red Bulls rode sniper Bradley Wright-Phillips and schemer Sacha Kljestan to the 2016 Shield.

The defending MLS Cup champions in Portland are inspired by Fanendo Adi and Diego Valeri, while up the Cascadia coast in Seattle, a new pairing – Clint Dempsey and Nicolas Lodeiro – has sparked a late-summer renaissance.

Cast your vote now to register your favorite twosome.

Or perhaps you prefer another duo elsewhere in the league, like Sebastian Giovinco and Jozy Altidore in Toronto, or Montreal's Didier Drogba-Ignacio Piatti combo? You can enter those or other write-in picks in the comments section.
