Hi All, I currently dive a Poseidon besea w100 and I really don't get on with it so want to move to a 'proper' bp&w setup. I've currently got an Apeks D45 but still need a backplate and harness. I'm always drysuit, don't need to travel abroad with it and I wear faber twin 12's. I normally have 17Kg of lead (I think I'm slightly overweighted but not hugely). I've been advised to get an aluminium backplate because it's light and makes rib diving easier however, I don't really see the disadvantage in going stainless? I had my eye in fact on a heavy 5mm stainless to get rid of some of the lead from my weight harness but apparently, this isn't a good idea? Overall just feeling a bit confused and have been told alu is the way to go and no more than 3mm stainless at most but am failing to see what the disadvantages in moving so weight on to the rig is? I know it will be heavier for rib diving but I'm sure I can deal with it. Also at the moment my feet are a bit negative so surely a decent backplate will go some way to sorting this out. Any advice greatly received, cheers!
