Man, it doesnt really changes anything if you go to TH9 if you talk about farming. I've been barching at th6, 7, 8 and 9 and tbh I never felt any big difference about it being harder or easier to farm from a th to another. I'd say go to TH9, maxed out Barbs n Archers to get easier 50% and stay at the range you want, feel cool with maxed out stuff, donate maxed archers, but at the very end it won't change that much. I'd go for th9 if I were you
