I have this setup, I assume you have the Zen 170mm dome. I have two combinations I use:
170mm dome with 12-40/7-14mm and on each side one INON M float arm and one ML. Buoyancy is 135+135+210+210 = 690 gr buoyancy.
100mm Zen fisheye dome or 60mm macro flat port one INON Mega float arm S and one 8" nauticam regular arm each side. Buoyancy is 2x 390 gr = 780 gr.
The dome setup is near neutral and the second combo is too much with the 170mm dome and it goes positive. The second combo is slightly heavier UW.
I use the Nauticam long clamps as the middle clamp as it allows the arms to fold closer together. The clamp going on the ball mount on each side is a long clamp with a shackle to attache a lanyard. The advantage there is the clamp handle does not hit the shackle when attached.
If you want a combo that does both pick the first one - it's 100gr heavier UW, but it works OK. You don't want a positive setup, so the second combo can't be used with the dome.
