I love my NF's (SHV and NX8) but would also suggest you look at Trijicon. I've got a Tenmile HX 3-18x44 in FFP and it's been rock solid. FFP can be a little hard to get used to if you're on the lower power, as the reticle becomes really small, but with the illumination I haven't had any issues. The center is the center no matter how big or small the reticle is. It's got exposed turrets, super reliable dialing, it's about as light as a reliable scope can be and seems to be tough as nails. I believe they make a version in SFP as well, but not too sure. I've never felt like 3x on the low end was too tight in this scope or any other, but if you got in a weird situation with dangerous game I get the point of the even lower power. I also don't really see black bears in the same light as a griz or African dangerous game.
All of this kind of depends on what kind of hunting you'll be doing....baits, hounds, from a stand, spot and stalk? About 99% of my hunting is spot and stalk, and just a little still hunting in between spotting so I've got a setup I can use for bear, deer, hogs and elk. I don't really have a dedicated rifle or scope for bear.
