Does anyone use a simple tilt head on their monopod ? i'm looking to use a waist support pouch rather than using the monopod on the ground. This gives more freedom of movement or fast action sports events. However I see that Manfrotto tilt heads are only safe for up to 2.5 kg. and I was hoping to use the same set up for my 300 f2.8 and possibly 500 f4 lenses. The 500 is 4 kg plus. Is anyone using this set up who could advise ? Im not really looking to use a mega expensive sophisticated set up, just something simple but tough.
