It is a method I really enjoy, but dont use much in the bay...
Our annual trip to the Solent after Smoothies always proves the method - it outfishes downtiders almost everytime - however the washing line across the tide can effect the weed.
James seems to pratise uptiding alot, or at least I think he does - he is often seem to be pendulum casting a 2lb lead, 8 squid and half a mackeral mounted on pennel 8/0's 40 yards uptide when fishing the ledge....I know as Ive been inches away from his end tackle on more than one occasion! - Charlie is right, take GREAT care uptiding in small boats.
