I am wondering what is better nickle or brass grommets? Also I have notice some use a belly grommet while others dont. Is this a preferance thing? Just curious.

soft wood grommets////hard wood no need

depends. i put the tail and front in on all plugs not made out of hardwood. swivel grommets, i only put on if i want to make something look perdy. normally my plugs will be lost before the wear from the swivel becomes too much of a problem.

i think you can start makin some plugs now spice. show us some pics when your done.
