Skip,
Both of those will work. Those types of lube are best if you melt them and dip your fiber wad in them and then let sit to cool. These work well for hunting where the gun may be carried for hours before being fired. This type of lube will not migrate into a powder charge.
When I just go out shooting, and the gun will not be loaded for any amount of time, I normally use vegetable oil to wet the fiber wads with. You don't want to make them dripping wet, just a quick dunk will do.
When you keep the fouling soft and under control, it will minimize leading in the bores. Similar to the function of grease grooves in a cast bullet.
