After taking advice from FROTHEY,RIK and boys in the past, ive experimented a bit with air drying / rehydrating baits.
Dave will correct me if i'm wrong, but with an air dried bait, which is rock hard, the boilie will nearly rehydrate itself with a dip or soak given enough time, but you'd be suprised!.. my home made, then air dried boilies have been in a source dip/additive for about 3months and they havn't fallen apart, just gone back to being the same consistency as a freezer bait, but full of flavour....
Putting these baits in cold water shows that the flavour will leek off VERY slowly, for, so far, about 4 days....
REMINDER... a strong bait is not good for every fishing situation!.
