Only one of each... I would pick my 3.6mm halo for lining, the hm Santa maria for shader. And the Diablo for color. An odd combo I know, but those just fit for me. Owl, the blunderbuss is an alright machine, I had to mod the original so suit me better. Its a beast for tribal now. The blunderbuss 2 is nice, but is quite large. I do like that it hasan adjustable stroke. I keep it set to 4.2 .it can feel a bit unbalanced though because of its size.but its a power house. All of these are nice machines, some better tthan others thanks for the compliments. Also, nothing but love for my halos
