I have shot hundreds of Flu Flus out of the Ugly Cookie [WB] ...
3 Feather, 4 feather, and Six feather...the key is using real feathers ...
I have boxes of turkey feathers in white ,red and yellow, full size foot long, so one can get three Four inch "vanes' per feather...
The six feather drops quickly, great for grouse etc on ground and in trees, the 4 feather has a little more distance, the three will give longer distance for geese...
Even thou the feathers are two inch wide they fly ok thru the Ugly Cookies, whether you buy or make your own put a good drop of fletch glue like Bohning Platinum on front and rear of feather...front being most important...
Actually out of all the rests I have shot feather flu flus out of , I have had the most success with the Ugly Cookie [WB]
