Suffolk?
Off the top of my head, a few for you:
Gladwells at Copdock
Birds at Blakenham
Markham's on Woodbridge Road
Breakaway Tackle on Bramford Road
Stuart's Clay traps, Melton
Tackle Up, Bury St. Edmunds
Sax Angling, Back of market Saxmundham.
Of course I would recommend Gladwells, I work there, but I would say we have some of the best selection of rods, and nicest service going.
Birds may be the biggest tackle shop with most brands, but...
For obvious reasons I haven't been in another tackle shop for over a year, so I wouldn't say what stocks are like.
