The firefly reticle is thick. Very thick. I picked one up today that was already mounted on a rifle I bought. If it weren't for the good deal, I probably wouldn't have gotten the scope. I will say the clarity/quality of the optics were very good and to my eyes about the same as the Leuopold Vari-X III that I compared it to, side by side.
I too, would suggest you look through one before you commit to buy one. I have no doubt that this scope will perform fine for a hunting (not target) rifle, however it'll probably take some getting used too if you're not already familiar w/ heavy duplex reticles. And this one it the heaviest I've seen yet.
