Best Way to Wall Farm

I am currently a level 105, TH9 with all my defenses maxed. I am currently attempting to get all level 9 walls before upgrading TH and want to upgrade my heroes as much as I can. Does anyone have a suggestion as to how to go about this task quickly without using gems? I would appreciate it if you suggest one of my possible methods below or to suggest your own. Thanks! Base designs for your method of choice is also appreciated!
Idea 1: Farming Base + Trophy Push (for league bonus)
Idea 2: Trophy Base for league bonus
Idea 3: Farming Base, stay around 1600-1800 trophies.
