I currently use the mech. spitfire. I am seriously thinking of switching to g5 striker cause i believe sometimes my mech. doesnt open. I have killed alot of deer with them and some dont have much blood. My question is...What do I need to do to get em to fly right. I have read other posts it says to spin em on the tip or buy a spinner. I am using the 2" blazer vanes with no helical, Does this matter? I have a drop away rest too.
