Farming range help

Hey I am almost level 85 (200 exp left), TH9, Max balloons, Max Giants in a week, level 5 tier 1 troops. My question is what is the best farmin range for me? I am pulling in 3,500,000 gold/elixer a day in the gold 3 range but have heard crystal 1 - masters 3 works better even upto 5,000,000-6,000,000 a day. So can anyone verify that I will gain more loot in higher leagues?

Loot should be getting better the higher you go up...my clan mate was just in masters and said the loot was great

P.S- do you remember me i was a saturn elite member and helped you out in the feeder for awhile ign-jacob
