Looks like it is laid out way better than the original vest. I had to buy the external shovel holder to put the shovel on the outside because the bag had no room in it for anything.
No it takes the 1.0 canister, the packs take the new 2.0 they work the same as I have blown off quite a few of both the packs, float speed 17 and 27, Float Turbo 25, and the Vest.
