1. Yes the mesh is much stronger than normal skiens, so your baits will last longer in heavy current. The mesh is also useful for the eggs not tight in the skiens. These eggs would be worthless without the wrap.
2. Good eggs have a skien still attached so the bait loop has something to keep them in place.
3. They will work fine but they will be small.

I also prefer my eggs not to be in the mesh.
