Thanks Mark. This is very much my way of thinking. People seem to think that heavy baiting is the way to go but whilst I have had lots up to high sixes I have never had a 7 doing it. That tells me I have been unlucky, fishing the wrong swims (or the right swims at the wrong time) or a new approach is required.Assuming you're legering I used Kryston Krystonite Flourocarbon Coated Monofilament in 8lb for a hooklink for my Stour legering with boiles; yet to get a 7lber but had them well over 6lbs. The key to catching the chub was a very short hair and as little weight on the line as possible eg a link with just a SSG or two, that and making virtually no disturbance, hardly feeding at all, keeping very low at all times. I would hold the rod if possible and feed line from a loop in my left hand when I got a knock.
I have just made up some Cork ball waters that will negate the weight of the hook but will still (hopefully) sink. This may or may not be necessary. I will see. Interesting to hear your hooklength choice. I will look at that. Very light legering. I am in complete agreement about this and holding the line. I have tended to ease the rod towards the fish when I get a knock but the loop of line idea is a good one.
I have also used a bobbin where the current allows. This seems to work.
All good stuff.
