Attack strategy on storage bases

I've came across a lot of 250k+ TH8/9s with my farming armies lately. And they have been a major problem for me.
My army is

• 9 Giants
• 7 WB
• 45 Barbs
• 45 Goblins
• 51 Archers

As the WB AI implies, Wallbreakers aim for the closest wall with a building enclosed. This makes it effectively impossible to aim Wallbreakers at storage compartments deep in the Base. The first set of wallbreakers will breach the perimeter, but the second set will deviate completely off course and open a point defense compartment. This happens nearly every time with a well segmented Base. The third set will do much the same. Sometimes I use my T1 troops to try and breach the core, but the mortar makes short work of them.

Thoughts on how to combat this? Besides the obvious, which is to train more wall-breakers. I want to avoid that If I can though; my cook time is already ~20 minutes.

I keep 20 wbs in this case, use 10, build ten to replace them, have 20 just in case.

overall thoughh im finding flying troops far superior at higher levels.

Other than that, rage plus giants gets through walls fast.

I'm a bit like SuperHal.

I take 15 breakers to every battle; only use them if the resources are amazing and the core is hard to crack.

Most of the time I only need 2-4 of them which is very quick to re-train.
