Your a level 35 and shutting down decent players who have more experience, if you are th7 you probably would have bad advice anyway due to being premature. I'm sorry if that offends you but its not recommended to take advice from people with level 4 and 5 walls, as if they had good advice they wouldn't have such low walls,
Anyway 1000-1400 at th7 I liked to stay at 1100 or 1200.
