Default Barclone Cherokee Multistage Design

I was looking at the Barclone Cherokee Double-D design.
Why use a smaller fin for the booster stage than for the sustainer?
Is this for the look? I swapped the fins on the Cherokee Double-D design.
I had to increase the booster lenght from 3.5 to 3.75 to accomidate the
increased fin length, and gained 25 ft in max alt. I gained about 50 ft
in max alt. by using the smaller fin size on both stages and keeping the
booster body tube length of 3.5 in.
