Re: what broadheads to use?
I too, like fixed blades. I haven't met a crossbow yet that didn't like Razor Tricks, G5 Strikers and American Broadhead Company Sonics. I would give the edge to the G5 Strikers.
As far as fixed blade heads, don't buy into the "crossbow" packaging. Some will weigh more to assist FOC. This would be a good choice if your arrows do not have brass inserts. Some "crossbow" packaging is just that, packaging. The head inside is the same, maybe a different color.
I support all hunters, regardless of weapon or technique!
