Thanks, the reason I asked about the liver is I've had good liver (BAF) some OK ones, and a vile one that ended up in the bin lol. In an ideal world it will be BAF quality.
I am trying to convince myself I can use any hydro to coat my banana baits (smellier the better for hydros is my thought usually) but seem to feel drawn to think I need sweet/nut type ones. But in reality shrimp or squid for instance would do a good job,
