I know the name of the knot, but I'm not sure as how I see knowing the names of knots is any less "anal" than those who worry about a few FPS
Let me explain it this way. You know the difference between a broadhead and a fieldpoint so if somebody is telling you to install your broadhead in a particular manner and is using a picture of an arrow equipped with a fieldpoint to illustrate, wouldn't you be a bit puzzled?
The same holds true with knots or anything else. If you have no knowledge at all you are mislead, if you do have some knowledge of the subject then it is up to you to get it straight but I sure do question the source of the information from that point forward.
