I have a Manfrotto tripod that works great for my Vortex Razor HD 20-60-85, but I need a new head for it. I have looked at the pistol grip style and some of the others, but just want something that doesn't have multiple twist locks. I want something smooth and only has one adjustment. Help me out with any ideas? I do a lot of hunting away from the roads, so weight is important, but not the most important.
