whatever looks good for you. Enhancement mods basically depend on how you want it to look and how much you're looking to spend. Some of my friends wondered why I spent about $117 on mods to make my custom 98 look like the Alpha Black when I could've bought the Alpha Black for only $130 instead of spending about $270 on the custom 98 basic package and the mods to go with it since my custom 98 will be a backup gun.
