Recently upgraded to a nauticam housing for an Olympus em1 mkii and I've decided it's time to get some new arms. I've noticed with my previous set ups that my camera was never properly balanced and took a good amount of effort to hold up. With this new rig, its even heavier and actually has me worried. I know the weight characteristics change underwater, but I was planning on upgrading my arms anyways right now. What is a good amount of buoyancy to start adding?? (i.e. how wide of arms in general or how buoyant?)
Looking at using a 170mm glass port with Panasonic 7-14 and an Olympus 8mm as well as the n85 flat port with the Olympus 60mm.
p.s. foam floats vs those float arms, is there a real advantage to the float arms or do they just look nicer?
