RE: is whisker biscuit a good choice
They are very good rests and my accuracy is excellent with it all the way to 70 yrds. I completely suprised some folks this week by shooting 4-5" groups at 70 yrds with several arrows touching!!
Speed loss is minimal 2- 5 fps ! 5 fps isn' t enough to even worry about IMO!!
Fletching wear can be an issue ......but a quality fletch with a dab of extra glue on the front of each fletching will perform very well. A straight or offset fletch will hold up better and lose less speed than a full helical through the WB .
I just got back from a hunting trip and 6 out of 7 hunters there were shooting WB and one of the 6 is a guy that has killed 600 plus animals with a bow . And has taken many/many animals in Africa and elsewhere at ranges of 60-85 yrds !! I' ll take his word on eqipment any day !!
