I've been using Maxima Red arrows for the last couple of years and have been pretty happy (although with repetitive shooting the outer covering tends to crack weakening the arrow), but on a friend's recommendation, I bought a half dozen Easton FMJ arrows to try.
So far, I think I'm going to like them. They're heavier for sure (on average about 40ish grains heavier) and that added weight is giving considerably more penetration on my targets. I can tell that they're flying a little slower, though and I hope that won't be a factor with string jump. I had to recalibrate my Spot Hogg to accommodate the different arrow weight and it was quite a change, but they're extremely consistent in flight and pull out of my targets easily whereas the Maximas was a struggle which leads me to believe that it'll lead to more pass throughs.
Long story short, if anyone is considering them, they're worth the money.
