I'm pretty new to bowhunting and I am shooting my dad's 1970 bear kodiak hunter #55. I need to get some broadheads for it and I'm liking the looks of the stinger broadheads and I was wondering if anyone has any experience or know anything of them. I was wondering if the bleeder blades negatively affect flight or penetration. And also if the serrated edges really make a difference or if it is just good advertising, and also if there are any cons for them, such as durablility or sharpness. Oh and I am thinking 100 gr for a flatter flight path than 125 gr, am I right?
