Hi Kingkarper,
If it's a stillwater then I'd be inclined to leger worm with chopped worm in a cage feeder. Crunch the end of the feeder over to stop them falling out and plug the top end with a small amount of either groundbait or even mud
Absolutely deadly [

]
You could also use corn mixed in with the worm to pad it out a bit and alternate between corn and worm on the hook
If the water is shallow and using a pole then try the same but cup in chopped worm and corn.
Sometime for a bonus fish, try using worm and a pice of corn together as a cocktail
Good luck,
Dave
