I have to agree to the review, based on my past experience using liftbag:
"...there are problems with using lift bags as marking devices. Without a load on the lift bag, upon reaching the surface, it often flops over and deflates. If this happens, the bag may actually begin to sink and be rendered useless."

I once borrowed Seademon's liftbag (forgot to bring mine for the trip) and used it as a marker during a deco stop; of course, so there was no load. I was trying to hang on to it, but at the surface, it flopped over and water got in. I was a bit yo-yo while doing that 20-min stop.

I should carry both, a liftbag and smb--like seademon normally does.

Again how much Kg/Lb liftbag do you guys normally carry during the dive. I normally use 25Kg when I go diving. During decos normally I'll deploy the liftbag.  Nice to have marked bouy as well. Lift bag behind my storage pack and marked bouy on my left thigh.Depend on the dives, Steel double tank, extra deco bottle, scooter and etc..I might bring my 50kg lift bag, in case something happen during the dives. !

Most common problem deployment lift bag is NOT ENOUGH AIR INSIDE THE LIFT. Happen to me before, Shit ! Of course you need practice to master the skill.

Safe diving.

Bijan, as mentioned in the article, a lift bag can still be used as a marker BUT it has its limitations as mentioned in the article too. In summary, it is best to use a Lift Bag as a medium to carry stuff eg mentioned by macha and a SMB used as a marker for visibility concern.

Nihaza also gives a good example of lift bag usage where he use it for decos as in my opinion since lift bags has a wider surface area it is more stable to hang on to it rather than using a SMB.
