One of things I would like to see with bait flavourings is multi flavour/shape containers -like testers- each with a pull off foil top, so you can try a couple of different colours/shapes to see what works before you open up a full tin or packet( a bit like paint testers).
So often I waste a full tin of plain,tutti fruityor red corn only to find its not working when I only want a few different grains to see if it works. One could do the same with soft pellets of different sizes and flavours. How about suggeting it Neil?
