Sadly I have had to do a bit of an edit, so this thread doesn't read as well as I had to take out a few debatable posts.
We can get back to specialised hookbaits, what makes them work?
Is it the flavour combination, the attractor package, or additional ingredients, even the ph of the lake or in that area?
We keep going round in circles, and its possible that glycerine is an attractor, or maybe the flavour itself, be it spicy or the base of a product.
Vanillin, iso-eugenol, glycerine, black pepper oil, garlic oil, bromelain or n-butyric acid all have their place, maybe even lemon juice or citric acid or flavours containing terpenes
