Well, that's a little subjective. The testing I did w/ them indicated they were better than 4" vanes and just as good as 5" feathers. The advantage over feathers is obvious.....it don't hurt to get them wet.

Blazers weigh less than a 4" vane, so you will gain a tad more speed, though not much, but your FOC could be improved if it is too low. Of the 3, Blazers are also far more durable. I can say one thing w/ certainty.....if you decide on the Blazers, you won't be disappointed.
