Hello Shoal, and everyone!
Okay first question - mounting to a standard backplate.
We tried to engineer our cell to fit as many different plates and systems as we could, so it depends on the plate and / or single tank adaptor. If there are slots for webbing in both, you should be able to weave the tank straps through the whole assembly with no problem. We can also place a set of SS grommets down the middle of the cell, spaced 11 inches apart for a couple bucks extra. We made the middle portion with heavy nylon webbing for this reason, so just let us know how you'd like it.
The rest of the world -
Yes, we do ship internationally, our ad was written a bit weird in that regard, and the designer has been flogged. We meant that the fixed shipping charge only applies to USA; other countries are based on actual cost.
I checked out the Roger Lacasse design, the measurements look pretty standard to me, so it should work just fine for your endeavors. As long as it's 316L or better, it should be great.
The urethane bladder -
Is one piece, ultrasonically welded. Just unzip the zipper that goes around the inside of the cell, and you can pull it right out. We made the bladder with the 'smooth' urethane, to facilitate easy repairs, and it's protected with a urethane-backed nylon inner 'sleeve.'
Connor -
I used TransPac II's as well, before switching to the BP harness setup. I think Dive Rite makes good stuff, and was really happy with it.
For traveling divers, we also make an ABS plate, and a Titanium plate. (Were out of Ti until after the first of the year...) My own 'recreational' harness with the SS plate compacts into a size that will fit into a briefcase (for those quick lunch break at the office dives) and only weighs about 9 pounds.
I took it to Roatan with me, and it was great because I needed no weight at all with the negative weight provided by the plate. I'm pretty skinny though, and even here in CA with a drysuit, I only use 10 - 12 LBS. They'll certainly want to see what's inside your bag at the airport though...
As far as the spine thing, we don't notice any problems, but are very open to introducing a pad if there is demand for it. At this point, it may be in the works anyway, because I think DocMartin is right, there is the perception of it being uncomfortable for some. If customers want a pad, we're going to make them happy.
We're also trying to keep moving on doubles plates, a larger air cell, integrated weight pouches, and so on. We're still new, and pretty small, so it takes time.
Have a great day everyone!
