I agree, I can't see any reason for not shooting the 2" blazers. Feathers have always been more forgiving vs plastic but require some sort of moisture resistant material to hunt in the rain/snow. I can't say that bisket rests are better or worse than other rests, I can say I do believe the fall away rests at this moment give the fastest arrow speed. I'm sure something new will come along and replace it. The old theory was 2" of vane would not stableize the new fast arrow speeds with fixed broadheads, this has been debunked, period. Shoot what gives you the best accuracy, even sacrifice some speed, and be happy with your results.
