ok my opinion for what it is worth , I have the Wimberley 2, lens master rh2 , and a heavy ball head, all handle my lenses for wildlife on mainly my carbon fibre monopod, I should say that my lenses are all heavy primes 300mm 2.8 , 400mm 4.5 , 500mm 4.5 , pick of the bunch is the ball head for no other reason than its more compact, the Wimberley is awesome but heavy, and the lens master is really good I have had the shortest time but was surprised by its size weight and build quality, I had some how thought it would be lighter and made from thinner alloy, I don't like the cheap lens plates supplied with it but that's just because they tend to let heavy lenses twist on the plates
