Dry Brine all the way. I have been doing this for about 15 yrs after experiencing all the headaches with wet brine, colors etc. I do very well with Dry Brine. I have even converted alot of my friends. I have used up to 2 year old bait. I put my bait box right in the freezer after each use. About 2 days before I go. I put salt right onto the anchovy tray. Leave it for a couple days. Bait is like leather after about 1 week. Its last for every. I caught my biggest fish 32 lbs on 1 year old bait. I figured out after all these years that its all about the roll, leader length and speed and that if there is fish around they will eat just about anything.
Good luck to all the Master Baiters on here but DRY BRINE ALL THE WAY.
