Excal's are the best so forget the rest! Ya i am a one point of view and won't change CB'sfer no one! Yup you can use same B'Heads just sight'em at your range of comfort. My max is 35 yds. on a calm deer. Yes you cut full length arrows off at where they were fletched end. I use alum. 2213's fer 3-D shoots and 2216's fer deer and my heavy logs 2219's fer anything i want to shoot thru and go 30 yds. the other side. I like Excal's cause they are simple to work on and the best CB fer yer money. Accurate and fast solid performing CB![8D]
