How can you compare Pike fishing to fishing for Chub.
Anyone setting out to catch a Chub isn't going to use a trace like they would for Pike fishing.
Yes, you can catch a Roach etc when Chub Fishing, but you rig up according to the species you are targeting, and for Chub fishing i have used hair rigs to good effect, i would also use bait straight on a hook i.e Maggots, Casters, Corn, Luncheon Meat, Pellets, but i wouldn't be worried about hair rigging baits as well.
If you haven't tried hair rigged Raw Stewing Steak for Chub, you should try it, you may just be surprised at the Bites you get.
The reason i hair rigged the stewing steak is because, the meat swells up considerably, and i used Kryston Silkworm Braid for the Hook Length, tied to a size 8 Kamasan Salmon and Trout Hook.
