Time to change my hoses, so I'm thinking of switching to flex hoses. I currently have 28" reg, 26" inflator/air2 and a 30 inch back up spg; I use ai computer. I didn't see a 28 inch flex hose, so I can go to a 26", which I have plenty of hose, don't know if would affect air share if needed. Thought about switching to a 40" and route under the arm style. Would I need a swivel to route flex hose under arm? Would the flex hose with the built in swivel be good or do I need to go standard flex and add a swivel? Open to any ideas or suggestions. I just do rec diving. I could stay standard over shoulder routing and do 26" or 30" flex hose, just don't won't big halo.
