I fletched up 7 arrows with 3 of the Flex Fletch 2.5 Pro vanes to experiment with. I have refrained from posting until I could be positive about their performance good or bad. I have been shooting them for a couple of weeks. Previously, I shot blazers for the last 10 years or so and before that, AAE Max hunters. nothing wrong with the blazers, I just like experimenting and tweaking my setup. I do not shoot a fixed blade broadhead, so I cannot speak to how they would do with that. I shoot Rage Extreme 2 blade broadheads. I found that the vanes shot very well with my Easton Axis 5MM arrows. They grouped well with little adjustment. I only shot them out to 50 yards. I found that they shot a little flatter than the blazers and my arrows were slamming into the target perfectly parallel. I shot them one day in about a 7-8 MPH crosswind and noticed very minimal wind drift. Just to make sure everything would be good, I did shoot 6 Rage Extremes at 50 yards and they grouped with my field points. I also appreciated how well these fletched up. I used the primer pen and glue from flex fletch and they set up very clean. Today I damaged a vane and tried to pull the other 2 off by hand and could not do it. Had to take my arrow stripping tool to it. i shoot a Ultra Rest dropaway and wanted to see if the lower height vanes would allow me to shoot cock vane down with out any contact. I shot 30 or 40 arrows with the cock vane down and never interrupted arrow flight. so, thats a bonus if you like to shoot arrows with all 3 vanes the same color. End result, I really like these vanes and they will be on my hunting setup until I find something better. Like I said, I like experimenting and looking for the next best thing.
