The force of the current on the diver is independent of the suspension
force on the line. In general practice a loop would be tied in the line
at the desired depth for a hand hold or to be clipped into for the deco
stop. Although I typically maintain neutral bouyancy, many divers in
cold water diving will hook into the ascent (normal line or emergency
ascent line) and positively inflate their dry suits for added thermal
comfort.
