Worth seeing if you have an animal feed company near by , they'll often do pellets and particles etc . As far as boilies go depends on quantity Abs bait , premier , retro , baitworks all do decent bait .
Couple of my mates are using Munch baits and catching I'm not 100% sure on quality due to the retail price but all depends what your looking for.
I f using pellets in quantity then your better of using coppens coarse pellet rather than oily trout pellet .
