slave cylinder or hose?

I have had intermittent problems with my clutch reservoir emptying out. It seemed during the summer months ie warm times it was fine, then when winter rolled through it would be a slow leak. Now its a full blown problem and empties out almost per drive. I will include pictures I took of it see what you think. I seem to think it is the line as the line does seem to have fluid on it, but there is fluid below the slave as well. Any thoughts are greatly appreciated.

My bet is on the slave, but replace the line first and see and if still leak then you know!
