In talking to another pilot who has an 172 L has states that his manual

I have a 172S manual It's my understanding that, in terms of flaps and
related performance, all models after L are exactly the same.

The newest (G1000) 172S manuals and checklist (and factory transition
training) say 0-10deg is approved, but 10deg is preferred to flaps up
in all conditions due to the decreased ground roll and increased climb
performance, and specifically called for when doing soft/rough field.
