trotting is a nice pleasurable way, rig wise keep it dead simple, plump and feel out the swim well and then just let the float and bait search out the swims for you.
At this time of year be mobile. Go as light as you can, if possible prebait 4/5 good looking swims and spend half an hour in each on rotation. Chub spook easily, in summer you can get round it on a good day by appealing to greed and getting them competing so much they dont care but in winter i wouldnt bank on more than a couple of chub from any one swim, certainly the case on small rivers.
bait wise as suggested above bread is awesome as long as its fairly clear, if the water is coloured i would go with lobworm, cheesepaste or luncheon meat, the stinkier the better. Boring as it is maggot scores very well but you wont discrimnate against everything else in the river like you do a bit more so with cheesepaste etc. On breadflake, meat and cheesepaste Id go as large as a six hook will help you single out the chub more too
i dont know what conditions are like on the wear, or where on the wear you are fishing but in general chub love snags particularly in flood they will hole up so try and trot down tight to features, chub particularly love undercut banks.
Chub are my favourite sport second only to barbel, in smaller rivers in particular they are an absolute delight to play and a beautiful looking fish, i am sure you will soon have the same impression
Oh as an afterthought - a good tip on feeding with chub, they provide a very good indication of whethetr you are feeding to much - as they have such huge mouths when you catch one have a look down - on maggots in the summer in particular its not uncommon to see chub absolutely full of them they have to be the greediest fish going
