AZ_Zoner:I think if the line kept you from being blow off a wreck, recovering the line would be a non-issue. You or someone else could do another dive and retrieve it. If you do get blow off a wreck, who knows, you might not have the opportunity to go on another dive.

I prefer "getting blown off the wreck" and ascending under my liftbag. That's SOP for technical diving on the wrecks here in Browad, Dade, and PB counties.
