There is no reason to modify the whisker. Looks can be deceiving!!
We have taken , Kudu, Warthog, Duiker, Pronghorn, Bear, Deer, all with the TURBO NOCK and the Whisker.
I have over 3000 shots on my whisker and have not have to change the brush and no wear on the nylon turbo.
I do a demo at hunting shows where I take a whisker and hold it vertically and drop a fletched arrow through it, It always gets hung up and the only way to get the arrow to pass through the biscuit is to give it a strong downward push. I drop a turbo and it slips right through.
I am attaching the photo of just one whisker kill
The reason for this is simple physics.
The larger the surface area of an object the more resistance or drag it has when passing through materials.
Three vanes have about 7 square inches of surface area and you can lose anywhere from 2 to 12 fps going through a whisker.
The DEADX with .8 sq in. basically slips right through the whisker.
The Hunter with 1.6 sq in does the same.
we could chrono no speed loss with the TURBO and the whisker.
This is the same reason why TURBOS also usually pass throug on a kill.
even though they are a rigid nylon they produce less drag going through an animal than vanes that have a much greater surface area.

I get this a lot at shows, People ask how can a hard vane pass through an animal, we have always used soft vanes?
I just ask them when is the last time they used a soft broadhead?
The hard ones pass through just fine?

The TURBO is not just another hyped gimmick, this in all honesty is
a new technology of arrow flight, and changes most of the rules we have grown accustomed to and feel safe with in our sport.
If a major archery company with a lot more funds than me would have invented this , you would in all likelyhood see them everywhere.

The TURBO for obvious reasons will be slow to be accepted by the mainstream archery industry. The formost reason is that it eliminates ,or at least has the potential to eliminate the fletching industry, which is a major source of revenue for manufacturers and dealers.
If you shoot a whisker Biscuit ,the average is about 50 to 60 shots and the vanes are ready to be refletched. If a shop does your fletching, that could be three to four times a year and you have spent two to three times what your original arrows cost, just in refletching. My turbos are at 3000 plus shots and still going! And the darn things ( if you set them up properly) work better!!
