Looking to replace ball head with pan tilt head on my Manfrotto Befree Advanced Carbon Fiber Travel Tripod. Found several options, their specs and info were very helpful in making a selection. Primarily photograph wildlife and needed a head that made tracking their movements easier. Frankly, the ball head that came with the tripod frustrated me, so I rarely used the tripod. As i have gotten older, holding up a 100-500mm lens gets tiring, looking for a solution to hand holding all that weight.
