RE: Blazer vanes lose of accuracy
Offset or helical is not the problem in this case.I have shot many straight vanes less than 2" long in competition and with great results.However,I do prefer offset or helical ESPECIALLY with broadheads.
Are you shooting a whisker bisuit.The stiff bristles might be the difference because the Blazersare probably stiffer than what you were shooting.
There may have been contact before and the Blazers are magnifying the problem because they are stiffer.
