Depends where your fishing I suppose, I had a great afternoon a few seasons ago on a moorland reservoir, that had a good head of chub as well as trout. I had 13 in a couple of hours.
I used a leaded, gold ribbed, hares ear nymph, with a slow retrieve. I guess you could fish a leaded nympth on a coarse rod, however you would be restricted in how far you could cast.
You could use a controller float and leave about 7 feet of leader under the float.
Why not get a cheap fly outfit and give it a go, it's not as difficult as it looks!
Good luck
