1) Yes, you should still breath the long hose. A wreck is still considered an overhead environment. You can share your primary reg much easier inside a wreck with the long hose. Your buddy can swim in front or behind you in an air-sharing emergency. You can get out of your "kit" and free your self much easier if you become entangled or pinned inside a wreck. 2) Butt mounting is not DIR. If the MLS2 is too big you should have bought an EE light. Butt mounting is bad because it screws up your trim. It prevents you from being truly horizontal in the water. Even if it was quickly ditchable with clips, it is not as ditchable as being on your waist. Besides it still is a metal to metal connection. Most importunately butt mounting is a serious entanglement hazard. You are alos not balanced properly with your stages clipped off on the left side. If you put the light on the right side of the harness and your stages on the left you will be balanced. Try wearing your big MLS on your wasit chances are you wont even feel it is back there. Slide another weight belt clamp on the strap to hold the light in place. 3) Redundant bladders are not appropriate for cave or wreck for several reasons and are not DIR. 1) You have the possibility of having two inflators sticking and flying to the surface as you figure out which one is stuck. 2) You don't need the extra bladder because you can only fill one fully at once, you don't gain lift from two bladders. 3) Your drysuit is a redundant flotation device. 4) If you are in open water than your lift bag is another redundant flotation device. 5) Finally you should not be overweighed in the first place. That means no steel stages and no steel tanks with a wetsuit you should be able to ascend by kicking to the surface.
