Tom,
Regarding the "snap set", you are exactly correct. Only inches in the line, not feet. This has to be determined by how deep and how far away your lure is when you set the hook. If it's windy, there will likely be some "belly" in your line. This has to all but be eliminated before the set. That's why I depend on a good 7:1 ratio reel and a longer rod (7-4 or 7-6).
As to your problem with Uncle Josh pork being too hard, I might suggest an old trick................add some Glycerine to the bottle. This seems to soften them right up!! If your concerned about the scent ( I personally haven't seen that it makes a difference scent-wise when I add Glycerine), add some J. J.'s Magic.
