You have to determine if this is caused by you or by equipment. Does it happen on every arrow or just some. Have you shot thru paper? Got a bullet hole? This is huge issue for you, because with out good arrow flight you will not get good penetration.
Also check and make sure that the blazer vanes aren't hitting your arrow rest. Blazer vanes have a higher profile (taller) than most other vanes and it could be that your vanes are contacting your arrow rest.
