good points yall. i just thought that the 4 blade would possible have a chance of a better blood trail and less chance of hole blockage. i shoot a bow prety good and always get a lung hit. just thought a little extra damage cant hurt anything. i have always shot the reg muzzy's but think im going to also go with the mx3.
as far as the 2 blade "bleeder blade as i call them" some have such a large blade span. some 2 1/2 inches. jeest seems to me like if the blade is turned the wrong way when it hits the chest it would hurt your penetration. if you watch the NAP broadhead videos allot of the shots arent complete passthru's. when i shoot a deer i want 2 holes.
