Planning Loch Etive trip.

I'm Planning a trip up to Loch Etive at the end of the month so i,ll probably not go out fishing again until then. I am going for a couple of days, will set up camp and fish through the night and try to get new species. I am aiming for spurdogs, thornback rays, gunard and wrasse. I,l need to head out and dig some bait before I go.
