I've nothing against other suppliers or shops but in my experience the most reliable quality bait is from James who's based at Framlingham (which is just up the road from Woodbridge). He also has a shop in Pakefield called 'Angling mad'. You can find him on here as 'james s-h'. I've also been very impressed with Sax Angling (Saxmundham) which is on your way to the beaches from Aldeborough northwards.
Hope you get in some good fishing and you've come just in time for the whiting.
