RE: Wisker " B" question ?
I posted this once from carolina archery here it is again. Hope it helps
Justin,
Thanks for taking the time to contact us. You can shoot any arrow you like
through the Whisker Biscuit. Our tests indicate that there will be some
speed loss if you use longer fletching and if you put more helical or offset
on them. Using more helical will increase the contact between the vanes and
the biscuit so more fletching wear should be expected. Some people are
trying to build an arrow with a specific purpose, like a large broadhead and
a heavy shaft for big game which may require more fletching to stabilize the
arrow in flight. The current trend is towards carbon arrows and they work
well with shorter fletching, say 4" instead of 5" . With the smaller shaft
sizes its difficult to assemble an arrow with a lot of helical because the
ends of the vanes want to lift up so its more common to see a slight offset
of 1 to 4 degrees. Around here, we shoot carbon arrows with a 4" vane or
feather using a slight offset of 1-2 degrees. With fixed blade broadheads
shot around 260 fps we are getting good arrow flight and broadhead control
out to 50 yards. Speed loss with this set up is only 1-2 fps. If you are
trying more offset, we would suggest using the tougher types of vanes
available from Flex-Fletch, Bohning, or AAE' s Speedflyte.
Hope this answers your question. Please feel free to call if you have any
other questions.
