diveprof, those are excellent points. My LDS is primary an Aqualung and Sherwood shop, so, from a service point of view, I would be covered. Regarding the mix'n'match approach of the kit, i understand that these would give less than optimal performances, but since I'm now diving with my family, including a 10 and 12 yrs old Junior Open Water, the next couple of years will be spent above 40 feet, in mostly easy to, maybe, moderate conditions. If the seller can agree to a decent price, then I think I'm good to go.Thank you
