You will not see a noticeable difference in pop between either option as they are held to the same performance standards, but I will say that there is not a better -11 bat on the market than the 2018 DeMarini CFX -11 Fastpitch Softball Bat: WTDXCFS. The 3-Fusion technology has increased the comfort on contact and the overall swing weight of the bat when compared directly to older model bats.
Yes, based on your daughters height and weight we would recommend the 2018 DeMarini CFX -11 Fastpitch Softball Bat: WTDXCFS in the 32"/21 ounce size.
Based on her age, our general recommendation would be for a 30" bat. However, if you wanted a bat into which she could grow with time, this 2018 DeMarini CFX -11 Fastpitch Softball Bat (WTDXCFS) in the 31"/20 oz would be a fine option to consider.
