most of the fishmeal groundbaits on the market will do the job fine.
i use ringers dark or dynamite green swim stim depending what my local shop has in stock, i use a bag of this with a bag of dynamite baits method mix, which is a spot on mix on i find. mix it the night before ideally.
Only have just started using Voodoo and is by far the best method mix I have used, I use it straight no add ins. Recently had fantastic sessions at Long Shaws and Ulcombe my swims turned into jacuzzi's with fish feeding on the bottom. THIS IS A TOP BAIT.
