Yes Dave, my thoughts - a great tool to learn an adapt.
I always assumed and so did others i have spoken to that the bait was fluttering between the lead and the boat, but in most cases i have seen, the boat on the surface is moving quite a bit faster than the bottom layer of water,
Oh, one note, is that live Weaver bait has a 100% success rate! (well, tried twice and landed 2 turbot)!!
