So, I'm shopping for my first BCD, and after reading a lot of posts here,....
My question then, is what would you say to talk me out of a high end back inflated jacket over a BP/W, something like the Zeagle Ranger.
If you've read the zillions of threads debating the advantages of BP/W vs back inflate BCs vs jacket BCs, then you've read pretty much everything anyone has to say on the whole issue.

The most useful answer you can get is to try out both, then decide what you like. Everything else is just someone else's opinion. Mine, for about the thousandth time (I just can't resist...) is that a rigid plate couples the cylinder to your back in a much more efficient way, and having the ballast on the plate between your lungs and the wing is an ideal weight distribution, especially with aluminum tanks.
For someone in your situation, deep sea supply makes a lot of sense, because Tobin can answer any question you might have, make expert recommendations about the rig, and if you don't like it, you could probably sell it immediately in the classifieds here on SB for close to what you paid.
The ranger is a big, bulky, high lift BC, not what I would like at all for warm water diving, but again, all of this is opinion. You really have to try things out.
