I think you' ve either gotten some bad advice along your learning curve, or you always choose the easy way out. Now before you get pissed, pay attention. You miss badly with fixed broadheads, you slap on some mechanicals.
You can' t bloodtrail, so you slap on a string tracker.

Thats how I read it anyway. I think you need to stick around this site and the technical forum for a bit. Ask lots of questions on form, practice, tuning, ect. There is a lot of information to be gained from hanging around here. The more you put into it, the more you' ll get out of it.
