Well I had four arrows that needed refletching and stopped by the proshop last night and picked up some of the Blazer 2.5''vanes to try out and I must say I am very impressed. You know how alot of products come and go claiming to produce fabulous results but often times fall short? Well not the case here!!! I fletched the Blazers on last night and got up early this morning to give them a try. WOW!!!My40yd.groups have shrunk and now look like my 20yd. groups. They seem to be quieter also and much more durable and at the same time I was able to shave 6 grains off each arrow. Only thing I could see that could be a problem would be clearance. Which is not a issue w/ my setup since I shoot a drop-away but the fletching are a little taller and might be a issue with some TM style rests. Just wanted to pass along my good results out of this product so that others might be able to benefit from them. My brother has been shooting the Quikspins and for less money and less added weight to his arrow I am going to recommend the Blazers to him as well.
