I tried a few ffp scopes, none of the realy expensive ones mind, and I decided I just don't realy like them for what I do. For target shooting I think they are pretty cool, especially if your using your reticle to range known size targets.
If i had to suggest one tho it would probably be a Burris veracity, I've only handled one, but I really liked it. Much more than the pa my brother in law has, and I thought it was better than the swfa two my buddies have.
I've never handled the Athlon with FFP reticles, but I really like the regular SFP Argos series I have.
