So I have a Glidecam HD 2000 I am balancing it with my Canon 70D (755g (1.7 lb)) and my lens is the Canon 10-18mm (8.5 ounces or 0.5291 lbs), a am using the Manfrotto 394 RC4 tripod mount (weighing 9.9 ounces) I am struggling to balance it and have struggled for months. I was using one counterweight on both sides on the bottom and someone told me more weight was better for top and bottom. So I put two and tried to mount counterweights on top but have failed so far. Has anyone got any suggestions for me on how I can balance this? and whether adding weight on top is better?
