What kind of head? Mechanical?
Why do you ask? Do fixed-blades always provide a pass-through?
No! But I certainly believe good fixed head with a moderately heavy arrow will increase the chances over a light arrow with a mechanical.
Uh, ok. I guess you know his setup already.
No, I don't. That's why I asked. I don't like mechanicals and I'm prejudiced against them, but I always want to know if my assumptions are correct or if I need to rethink my ideas.
