I don't know if it's just me, but along with using FAR, it's way harder for me to launch rockets with "cannonball" crew module than with the stock one. It makes it nearly impossible to make a gravity turn, the top behaves like it was way heavier. After turning the rocket at ~50-90 m/s there's no way to tweak the angle, it just goes down and stalls. Changing module to stock fixes the issue, although it's heavier than the first one introduced with the mod.
