Eh Tsunade/Ay/3rd Raikage/Akamichi (the guy who creates a mountain)/Sakura and etc can easily beat Choji.
Choji needs size to be on the same level of strength as Sakura. Which is a plus and a minus. With Sakura's skill in chakra control and etc, Choji is pretty much done mate.
Even Choji's dad has it (i think, not completely sure). And he wasn't even put on Tsunade's level or any of the sanin. So yea, Sakura can pretty much either low-diff, or mid-diff it.
PS: Alot of ninja can just climb up choji, and take him by his vital organs, especially a medical ninja who knows the body.
