'I've heard it can be difficult at depth to start moving back up toward the surface.'

I remember a few dives at 80-90 feet, my super-soft spearfishing fins, big cannon with reel and 20-24# of lead but even the one where the fin pocket tore out, I didn't have to 'donate' a weight belt.

Now-a-days at double that depth I'll take an extra second or two to get a good pull on the rope and not have to kick two or three times to feel like you're moving.
