Trancer, I would definitely suggest you experiment with flavours when lure fishing.
While in Australia I fished extensively with an angler who was at the top of his game. He caught more fishing than most people and consequently was sponsored by a couple of big fishing companies. Sure, he was more knowledgeable than most anglers, but he also swore by flavouring his lures. We mainly fished butterfly/vertical jigs and he would never send one down without giving it a good flavouring. And believe me it did give him an edge, particularly when the fish were being finicky.
I also heard of an angler from Goa who would always fish with a small pouch/reservoir attached to his belt, which contained fish oil. Before every cast he would dip his lure into the oil and give it a good coating of oil. And I can confirm this angler caught far more fish than most of the other anglers....Whether the oil gave him an edge is the question....something to think about..:)
It's important to remember when lure fishing that once a fish becomes aware of your lure (by sound/vibration or sight), it might not directly take it. Most fish are quite capable of inspecting the offering before making the decision to actually strike or not. This is true not only for short distance/ambush species such as barramundi and jacks etc (i've seen barra and jacks inspect and turn from my lure many many times) but also faster pelagic species such as spanish mackerel and wahoo.
So sometimes when the fish are not feeding confidently, a bit of scent on the lure may seal the deal and actually get the fish to strike. It seems sensible to try and give yourself an edge, so why not try some experiments. Just make sure your lure action is not affected if you try adding a scent dispenser above. You could make start with some soft plastic lures which will actually soak up the scent very easily ( there is a reason why many Australians think that anglers who use Berkley gulp soft plastics are cheating)
Oh and Ken!!.... you have finally surfaced.. I was beginning to think you may have turned into a fish or even a monk!
All the best, Scott
