If you can spare the $15, I would recommend you melt your base hornet, plus the Super Hornet add on (110 base hornet + 55 super hornet). And spend the $180 on the weekend warrior package. You get a special side arm (wooo) but for $15 you get a whole package deal, so either a NPC or another character.
Just don't melt the military hornet upgrade which was the "cosmetic" change.
