When fishing with hookers, I use the brand which are called jellets and normally the natural flavour. I use this because this is the flavour that the owners normally feed the fish on anyway.
When feeding them, i will use one on the hook, (2 Depending if theres a few bigger fish in the swim) and will maybe cup one or two in with the normal smaller feed pellets.
If fish are up in the water then i will cup 4 or 5 in every minute or so and keep lifting my hookbait to make it look like its loosefeed.
Anyway, Hope this helps
Michael!
