Launching a blob doesn't need to be a big chore.
Here is a video of me launching a blob at my leisure while swimming into a non trivial current (watch the bubbles, the particles in the water and the angle of the line).
This is a real-world video, not like the demonstration videos done with perfect buoyancy in completely still water. This is what it looks like when you do it during a real ocean dive in real conditions. I wasn't initially aware that my buddy was filming me or I would have posed for the shot and hung completely still.
