After reading the FOC-Fletch post, I did some modifications to a couple arrows last night. I stripped my beman classics of the 3-5 1/2" shield cut feathers and went to 4- 4" parabolic feathers.
I had my nephew standing (safely) near my target and shot a few different times. With our scientific testing- we both thought the 4 fletch was quieter. From my vantage point- I could see the revolution better- and thought the 4 fletch became more visable due to the rotation. Not sure if it was just a brain teaser- but it surely looked like I could see it spinning better.
I plan to do some longer range shooting and see what the results are: my biggest question- will the one extra feather cause noticable drag- enough to slow the arrow down at 35-40 yards???
Testing tonight, won't be able to post results until Tuesday- busy weekend planned, and steelhead fishing on Monday.....
If anyone can add their opinions- please do so- I would like to hear what others have found with this set up. Thanks
