I have been shooting the vmaxx's for a while now. They 4" ones weigh in at 7 grains a piece, and they seem much more durable than any other vane I have used in the past, plus they are so darn cheap. I have not tried the blazers yet, because I shoot bowhunter class in 3D and need a 4" vane but I have heard they are pretty durable too. I have used plastifletches, and duravanes in the past, and the vanetecs are more durable than either of them, plus there is no cleaning/prep work on the vane itself. They are a dream to fletch as long as the shaft itself is clean. I now end up refletching arrows a lot less from nicked up vanes with these, I think I have ruined 2 vanes in the last 6 weeks or so from tight groups, when I used to ruin 1-2 per shootin session. I can guarantee the lack of ruined vanes isn't from the size of the groups either...........
