Big stick,

Eggs are not eggs and cure is not cure. Though it is more important where to put the bait rather than what is on it. It does seem to help if you have taken every step in preparing the very best egg you can.

I've spent 20 years fishing in Alaska and all over the NW. Most fish fall to the average egg really well. Even those in Alaska can be picky at times. It never hurts to open your mind to cures other than the commercial types.
The maturity of the egg makes a huge differnce in the quality of the finished product. Though an immature egg may present itself better to the user, the fish may like the most mature of eggs you can get.
