My brother owns the Ralf Tech Travelight and I own the WR1 bcd.
Why did we chose ralf tech? because of the quality it imposes. It's been 2 years with the equipment and feels like new.
I recommed the travelight if you're going often on trips and like to scuba dive. Why? because it is the lightest bcd in the market. I recommend the Cocoon Tech if you're a new diver because of the highest stability at the surface (yes, two people I know have the cocoon tech and I tried it) but ... the WR1 BCD is my favorite! The shop I go to is great and you could purchase it online at
ACROTECH SCUBA the name of the shop is called ACROTECH SCUBA.
Just a tip... their suits, gloves, and boots are beyond great. I had such a great experience with Ralf Tech... and I am happy!
Another place you want to check out the ralf tech equipment besides the above shop is:
AQUADIS Corp Homepage
Take care and have a nice day!
