Which solo is best for xp grinding?

Field goal is the fastest. About 500xp per minute. About a level every half hour. Field goal has no celebration and is super fast. No benefit of the TD or yards toward Ultimate champion though.

It would be a king and monotonous journey. Is that really what you want out of the game? It would take you forever to level up and you would get sick of it. Just play it and level up based on your play and stop looking for a shortcut!

Either would be if you didn't have to back out from dashboard between every solo.
