Matt,

The advise pertaining to KE and mechanicals you are giving the Nuge is great. However, you are using " abouts" to use your words when calculating the Nuge' s speed and KE in my opinion. I have been at this for the better part of 15 years now and in my opinion (everybody does have one ) if there is any doubt pertaining to potential performance of a mechanical head due to lack of KE, then the best way to go is a fixed blade broadhead hands down. While I agree that there are mechanicals that open faster and have smaller cutting diameters that would work more favorably with a lower KE setup, why chance it when you know a fixed head will do the job every time. This is not meant to be a fixed versus mechanical argument, but with what we know at present about the Nuge' s setup, a fixed blade design is going to work for certain.
