As is the snowmobile line of vario ABS packs.
I prefer ABS for a ton of reasons.
2 bags, better trigger, lighter bag, no leakage from the cylinder, orientation of the bags when deployed, cylinder takes up less weight in the pack, compression straps (still don't understand why bca won't put them on their packs... I HATE having stuff flop around in the pack behind me),shovel on the outside of the pack, a pack I can put different bags on so I'm not tied to one size for the kind of $$ we spend...
This is what I run, a snowmobile specific bag.
but I also have the bag from this one, that I can put on if I want 18 liters
and the bag from this one in case I'm heading to a hut trip or filming that day
IMO, the ABS pack is far superior, but you pay for it.

We just bought 2 of the ABS Vario systems with a number of different packs for each to suit different conditions and needs. We bought them for most of the reasons outlined in this post . . . two bags (redundancy!), better trigger (patented!), lighter bag (not true in every case), no leakage from the cylinder (I haven't heard of any issues though every ABS cylinder is refilled by ABS and NOT by a local SCUBA shop. There are local retailers, however, that stock new ABS cylinders and allow you to trade in used cylinders for ~$40), orientation of the bags when deployed (this is personal preference and I'm not convinced the existing data has credibly proven that one orientation dominates the others), and multiple backpack size options that zip into the base Vario unit (very useful as I do a lot of b/c skiing and SAR work too). I'm surprised how many purchasing comments I've seen on this thread that seem to lean toward BCA based primarily on their canisters. Is filling up a BCA canister locally with a $15 air charge SIGNIFICANTLY better than replacing an ABS nitrogen canister locally for $40??? Why make a purchasing decision based on a $25 difference in refill cost? How many times are riders planning to pull the trigger on these bags? There's a reason that every manufacturer except for ABS is using mechanical activation. ABS created the charged trigger activation and then patented the technology! I'm confident that if I ever have a reason to pull my trigger, the $25 extra dollars I'll incur to replace the canister will be the LAST item on my mind . . . I WANT THE BAG TO HAVE THE HIGHEST PROBABILITY OF DEPLOYING AS DESIGNED. All that said, the ABS bags will hurt your pocket and I'll give two thumbs up to anyone who rides in avalanche terrain and makes the smart decision to buy an air bag . . . regardless of brand!!! Stay safe out there guys because right now in most areas we're (sledders) still dying at a higher rate than any other group accessing avalanche terrain. Buy quality equipment, KNOW HOW TO USE IT, PRACTICE WITH IT, DEMAND YOUR BUDDIES DO THE SAME, SEEK TO CONTINUOUSLY IMPROVE YOUR AVALANCHE EDUCATION, USE YOUR BRAIN, have fun, and ride safe!
