Good choice!
Did you get the 26 torus wing? My DSS is the third BC ever since being certified. Was never contented with my two previous BP/W. compared with other brands, it is the most streamlined designed.
Although i cannot offer much tip as i've never known the difference in using a jacket type and a BP/W BC and the diving adjustments that needs to be made in switching from one set-up to another (immediately upon enrolling for an open water course and even prior to the start of the pool sessions, I've already bought my own complete set up, including a BP/W BC), the only thing i can offer is - just like any other BP/W, never fully inflate your BC at the end of the dive as the more inflated it is, the more tendency for your BC to push your face downwards.
To accessorize, since your in the Phils, you may want to visit some local dive shops such as Philtech (heard they moved to Quiapo, but has not yet visited their new location), 300 Bar (in Pasong Tamo), or Nautilus (Pasay Road).
