Q: 9. what's the best vest system for this glider? Also, is this better than a brushless gimbal?

A: We would suggest this vest: Glidecam Smooth Shooter Support System B&H # GLSS These two items are designed for each other.

A gimbal is more intuitive to use, more expensive, more complex and can do shots the other can't.
