So before I start I not saying the above is wrong, I am just offering an alternative view on what is happening to your bait.
So we air dry our baits why ? well usually to get more shelf life out of them, but what are we really doing to the bait itself, when you design a bait you want it to be moist in the centre it help it release the soluble attraction when the bait gets flooded with water, when you air dry you remove all the water from the bait so when they enter the water it takes a lot longer to get to this point, also are you dulling the effectiveness of the ingredients ? is the soluble content still has effective after the moisture has been removed from them, are they still even soluble ?, after air drying what you are left with ?
Hydration mainly used to re hydrate air dried baits right ?, How many re hydrate with a liquid similar to what was in the original bait ?, if not have you taken a bait and changed its profile from what you originally purchased as you may well have neutralised the original liquids that were in the boilie to start with.
All this said people still catch plenty of fish using this method but is what you have caught on a bait that has morphed from its original purchased state to a form of high level attractor bait as touched on by the scientist in his rotary entry and thats why it scores high.
Is all the above a bait industry tactic to sell more products from add on sales.
So there are plenty of thinking anglers present on this site, I would be interested in some of them's thoughts on the above subject.
