I have tried several types of tripod heads, and I am convinced the ball head (meaning its support is on a round steel ball fixture that can be locked down) is the way to go. I have tried pistol grips, 3 axis heads, and others. For the price, you are simply not going to find a better deal.
One knob to lock it down, the other for tension control. Simple. Effective. Inexpensive. I still have and use my original, which is going on 9 years now.
Highly Recommended.
