I never saw it on the forum (I haven't see everything I know...), but is there some people who make body quills for a predator chest and shoulders ?
Like these :
contact bountyhunter (brian)here on the lair or go thru ebay and contact him there(same handle)
he can make ou some for chap a set of quills go for 6.99
Froggy also makes quills ,or ultimately you cam make them yourself with supersculpey.
