Ausie-guy.
I have used Ribtecks and I don' t particularly like them at all. Ther' re not very strong or reliable, but they are pretty cheap. I' d probably only use ' em when hunting foxes or rabbits, anything larger and I find they don' t have the strength I' d like to have in a broadhead especially when it comes to punching through a pigs fighting pad or bone. But still some hunters use them for pigs and deer. The blackstump does them all so that' s all I use.
Cheers mate.
