welcome to the forum Kie, you will probably find that the ground bait hasn't changed much, still basically ground bread or soya flour, various flavorings such as turmeric, chilli, liquidized corn etc,etc.
a good favorite of mine is basically
liquidized bread (binder)
liquidized dog meal (bakers complete) food source)
ground halibut pellets (oil content)
paprika (colouring)
turmeric (spice)
chilli flake (why not?)
to change it up for the seasons i would replace the halibut pellets with liquidized fruit such as pineapple, strawberries etc.
sweetcorn, chick peas, mung beans or maples on the hook or you could find a good food source boilie to compliment the ground bait too.
thats my take on it bud, have fun and catch fish
