RE: is whisker biscuit a good choice
The way the WB gets " accuracy" is the MAKE the arrow start spinning faster sooner. This is why it can be " easy to tune" with broadheads...but with field points (which don' t need as much spin for accuracy) the benefit can be lost by the fact that the rest contacts the arrow for a VERY long time. This is where drop away rests shine.
When shooting a WB, make sure your using some offset or helical to your vanes...with straight vanes, you will gain no benefit with the WB...and may well loose accuracy.
