need some help please
 

i just bought some new arrows,they are fletched with a helicle. my old arrows were straight fletched,when i was shooting yesterday and 2day the helicled arrows wouldnt hit the same spot twice so i started shooting the straight fletched arrows i hit the bullseye everytime , QUESTION 1 WHY DONT THE SHOOT THE SAME THERE THE SAME ARROWS ,QUESTION 2 DOES HAVING A HELICLE MAKE YOUR ARROW LOSE SPEED ,AND QUESTION 3 WHAT WAY DO YOU PREFER AND ANY MORE INPUT WOULD BE USEFUL THANKS

I would like to hear the answers on this. I am getting ready to buy new arrows. Thinking of switching to blazers aswell.

Loss of speed would'nt affect accuracy, just point of impact. Theoretically the helical fletched arrows should be more accurate than the straight fletched ones. Perhaps the helical fletching is coming in contact with something on your bow on the way out which would set them off course.

X2. Im going to have to agree with wingbobe on this one. Sounds like a contact issue.
