Hello, I want to buy a side mount. My own choice is the armadillo or utd system. I measure 5.8 and weighs 190 pounds. I dive in cold water with a drysuit (Trilam). I like scuba equipment oms phantom lamp, two aluminum cylinders 80 '. The UTD harness with 20 pounds of wings seems interresting. A wing is 20 pounds enough? Again sorry for my English. I await your advice.
