Its funny how slightly front heavy became more exaggerated over time, it could be better, but its far from a dealbreaker.
Depends on Sensitvity and CPI, Fusion is worse at 800+ cpi and personally "feels" worse from 1m/s to ~2.6m/s due to low FPS of AM010, the jump to the Accelerometer/Gyro takes about 10ms and is slightly noticeable, the tracking of those two itself is actually very good, but it doesnt really matter at those speeds.
