Tagabuck, the subject of scentlock has come up on here, with opinions of "does it work?" and some folks feel insulted by the "forget the wind, and just hunt" marketing hype.
I'm not sure it's worth the money, but my wife bought most of my hunting stuff (!), and she thought it was a "good thing".
Also, the person that wrote the editorial letter that you mentioned, was also against bows with metal risers.
I guess if you are not dressed like him, with the bow he is using, you don't meet his standard.
That is just plain his problem, not mine.
Enjoy the gear you have!
Thanks,
Rich
