I have never been a person that held their rod high(like you see some do on T.V.). I feel that leaves you with no ability to pull the fish or make up slack when you need to. Your arms can only go in one direction......DOWN). That makes little/no sense to me. Get your arms up, yes but not so high you leave yourself...........STUCK.
As far as fighting them in a current....you can't. YOu have to let them go to an extent. If you can, try to move downstream with them(if conditions permit and it is safe to do so), otherwise let them make a run until they tire a bit, then 'work them'.
Good fishing technique trumps all.....wish I had it.
