hey I know - you want to try diving in the sea here - steaming spring tides, the line is usually at 45 degrees - and yes we have jellies too!!

I'd agree that current poses for more problems than vis or cold - but seeing as most people would not conduct a training course in significant current (unless no other option) , I don't think that really needs to be included in this discussion.

I was thinking more of a straight comparison in currentless, jelly fish less conditions between somewhere like Dahab and somewhere like a lake in the UK or Canada....
