Bulk spools of Daiwa Sensor or Maxima, in 12 or 15lbs bs are perfectly adequate. I tend to stick with Fox Easy Twist, in the 30lb test. Wobblers need little else in the way of end tackle. A few swan and AAA shots, a tub of line grease, and some corks or poppers are just about all you need. These and your bait supply can easily be carried in a light shoulder bag, together with unhooking gear, spare traces and bait.
Baits are usually coarse deads.
Our favourites are roach, rudd and chub. Get hold of one of those little freezer packs sold in DIY stores to keep them fresh in. If you've never wobbled, leave the rest of your gear behind the first couple of times you try it. Like anything else, it takes a while to master and if you take your chair, buzzers and all the rest of your kit, the chances are you'll end up resorting to your usual methods after a couple of blank swims. It's a great method for after-work sessions at this time of year.
