Here is the scenario.
I dive an OMS SS 6# plate with a Halcyon wing and a single webbing harness. I have usually dived a 3 mm suit and have put between 2-4 lbs on a cam band weight pouch. I have found that this gives me a good weight distribution and trim setup. I also have a Halcyon gear pouch and a small mask pouch that I switch out depending on what extra gear I am carrying (always a small knife, spool, and shears, but for night dives extra light, strobe in the bigger pouch) that goes on the right side at my hip. I have never been too concerned with ditchable weights since I always felt I could swim my rig up and I carry a 6' SMB and a spool that I can use as alternate lift.
I am contemplating getting a AL plate for travel since I need to watch weight on inter-island flights, but this would mean putting 4-6 lbs somewhere. I have never really worn a weight belt since I started with an WI BC and would prefer not to do this. I was looking at the OMS and Halcyon integrated options but was wondering if anyone had any experience with them or knew how they worked, placement etc. From what I can tell I will not be able to wear my pouch with them but it would give me the ability to ditch weight. They are also expensive. I may also get a 5mm wetsuit next so would need to add weight for that also.
