...So why the DSS Torus 26 vs. any other wing out there? A lot of companies make wings and the mounting all seems pretty standard.
DSS is just down the street and Tobin makes some quality gear. The Torus wing would be perfect for a single tank setup. That said, most wings are of decent quality but many are oversized (too much lift) for single tank diving.
I picked the Ventures just before they changed to a larger version and were selling them for $100 each. Hard to pass up.
As for buying the WTX. Aqualung/APEKS has many dealers in the states and Im sure with a few phone calls, you would be able to get one pretty easy. You might even find one on eBay or Craigslist.
