I'm also shooting the 2" Blazers, I like them because my arrows recover faster and I have a lot less cross wind interference. I have them straight. They tend, atleast for me shoot better at distances beyond 40 yrds.
I admit that when I purchased my arrows a few weeks ago, I picked the 4" vanes because I thought that was what an arrow was supposed to look like. Since then, I have read a few articles that, like the other posts, make a strong case for the shorter vanes. One of the other benefits I read is that the smaller vanes are less affected by the wind while the main redeeming quality of the longer vanes is that it is supposed to stabilize your arrow in flight better. Between everyones comments thus far and my research, I think I might have to give the 2" blazers a try.
What you really need to do is to go down to a archery center and find some arrows that will match your bow as far as length of pull and draw weight. Then shoot them to see just what they will do. An old bow that I have will not shoot arrows with only 3 vanes on them plain and simple I had to go to a 4 vane arrow along with a 4 blade broad head to stabilize the arrows. Now my newer bow shoots 4" 3 vane arrows with no problems but I have never shot the shorter vane arrows either. Perhaps they will make me a better shooter but then again they might not.
I have shot 4", 3" and now the 2" Blazers. I recently just switch to the 2" Blazer to lighten up my arrow a bit...500 grains with a 4" vane was just a bit too heavy. After I made the switch I wish I had done it along time ago. My arrows seem to fly better and my groups have increased....now that could be because I have been shooting more...who knows but none the less I am very pleased with my Blazer. Now I did try the 2" Fusions and did not get the same group results.....???
The record books, that are put out by Boone & Crocket and Pope & Young and where I live is Henry Kelsey they are a great way to research a state or a province for big game. This does take some time but the knowledge it gives you, can be very valuable. Not all hunters have their trophies recorded, as where I live after the Hanson Buck became the new world record typical Whitetail, we saw a flood of hunters and now that has happened, some hunters are shying away from the record books but...
