Less boosters are sometimes good. They aren't strictly necessary for efficiency, they just need to be used when you have a low power core stage. There's other options. I once modified the two stage rocket in my profile photo into a lean beast that was 25% payload. With two serial stages.
Congrats on the docking, I shall follow your career with great interest.
