My quess is you have some tuning issues(paper tuning by itself is useless).


I would also quess you have some form issues.

The reason I say this is because even an untuned bow can be shot well by someone that knows how to shoot right and consistant.


The more a bow is out of tune,the more unforgiving it becomes,so someone that has poor form has more trouble with an out of tune bow than one that has good form.


Fixed blade broadheads make an an out of tune bow almost impossible to shoot,even for a good archer.


Here is a thread on tuning I made some time back,this should help with the tuning aspect.

If you could post a picture or video of your form,from different angles,you could get help with that also.
