If I dont have the intentions of shooting a doe, I really have little to no need for them whatsoever. In the woods, I can see fine at the distances available without the use of glass....plus we almost always film our hunts, and camcorders have 20x zoom.

The only reason I see needing them is, like you said distinguishing bbs from slickheads.

That being said, I plan on picking up a decent but somewhat compact set of glass this winter.
