Berkley-fishing Trout Baits
Berkley-fishing PowerBait®

Not yet...

I've got a tub of the Berkley Powerbait Earthworms, I was thinking they might be an interesting option fished on a fly set up with a strike indicator as a float. Waiting for the season to open before I test this out - the theory being that it's similar to the method used in America when fishing natural baits on fly gear. No idea how I'll get on mind you but it gives me something to do.

Hi before I get shot down used it on Friday at Grassholme with my static caravan next door neighbour it works but there seems to be no skill in it,a means to stock the freezer, attach two beads to hook size 12/14/16 with an arlesey bomb for weight lob it and wait got our 8 each ,at least now I can concentrate on the noble art.Noel
