I've been shooting the whisker biscuit for4 years! Quick Tune/Nap prior to this. I do miss shooting my carbon tech Rhino's with helical 5 inch vanes however. NAP 2000 RG seems to be one to try. I have seen many drop's type rest dropped from mechanical failure tuning problem etc... over the years of 3D shoots. Latest one, was set without a string on cable. Dropped from the twang of the string, sound/vibration or pressure set it off I guess. At the end of the shoot, Matthad seen wear marks where as the shaft/blazers where making contact, like not dropping quick enough! I will check into the NAP 2000 RG. I have always liked there product and quality.
