Help me choose my little project!

Hi I have been wondering certain thing for longest time, so I have decided to test it out myself since I haven't been able to find answer for it. I need your help to choose it.

VOTE ON THIS POLL PLEASE

I'm trying to see if the enemy's level compared to your leads is a factor on chances of it dropping trophies after winning a battle with one. So all I need is the unfortunate target group I will be focused on beating up miserably until I get results. Please vote on your choice!
