.i was going to mention the AVON spray,but being me,youd of thought i was taking the P.as kayos says loads of good advice on the threads he has mentioned {top man mark}.3ft long normal paternoster rigs with 4 inches of wire or heavy braid on the hook length as the Spurs will bite through even 80lb mono.Strong 3/0 hooks.
Best bait by far for the Spurs and Thornies is a 2 inch piece of Launce Sandeel with a strip of Squid lashed to it.
Big tides are always better as well.
As for insect repellent,this is the best we have found.

Fished there quite abit over the last few years, also going up aug bank hol myself. we usually fish along bonawe quarry. Its really deep straight down the edge. Weve had many species from there spurs and rays on mackerel and squid. Pollock and sea trout on spinners and also gurnard, cod, whiting, lsd etc. we found that a string of baited hokkis lobbed into the middle about 80 yards is more then enough, its so deep and dark, they seem to like the illuminous glow of the heads... its about 500ft deep in places! you will have more luck for the spurs after dark, but all other species anytime. Also there are the self drive boats from TFC Boats, boat hire and fishing on Loch Etive in Taynuilt near Oban Scotland. good luck and enjoy.
Cheers mate and reggie looking forward to a long weekend away boys plenty of pics of fish i hope and a few new species tooAye mate 3/0 will do, strips of squid / mackerel / sandeel etc, cant fail mate.... Well it is fishing but that worked well for me having a species bash. Theres loads in the loch, including hake!
