TH9.5 and walls

Hello, this is me.

The 4x bonus is awesome, however my gold is now almost full and I'll have treasury overflowing again shortly. I'm afraid to start upgrading walls. I haven't added any of the new TH10 walls to date. The only defense I have done is AD. My gold upgrades are about to come to completion with the exception of a trap every few days.

Are there any .5 experts out there that can tell me whether I should upgrade walls or just forget about the gold for now? I'm a good farmer but hate to be wasteful. Thanks in advance.

Do the walls. They have weight but not too much.
