You don't need gloves specifically to dive a wreck since you shouldn't be touching it anyway...
That depends on what you mean by "dive a wreck". There's no need to wear gloves if you dive on a wreck. But uou'll be needing band-aids if you dive in a wreck without gloves.
Just like not touching the wreck, there's no good reason to touch the line. If you're in a current use a John line to hook in.
I'm curious how you'd use a jon-line to ascend on a line in current. Is this some sort of quasi-climbing adapted technique? Two jon-lines, used to progress upwards without touching the line? Tarzan-like, swinging from jon-line to jon-line? Or a 'rest..detach...kick-like-mad..re-attach...rest' sort of 'shuffle upwards' method?? Mystified....
Jon-lines are great for their intended purpose - extended stops in current, without stress on the arms (and reduced risk of DCS through limb immobility). I've never seen, or heard, of them used for an ascent though.. ?!?
