I've actually got the Vortex Viper PST 6-24x50 EBR-1 MOA FFP on order and I'm having second thoughts about just waiting for the Sightron S3 6-24x50 w/MOA SFP. I have owned a Sightron before and their optics seemed to better than my Luepold and I was really pleased with their product. I had read a lot about FFP vs. SFP. My question for anyone that can help is, how much if any benefit is the FFP over the SFP reticules? I was able to look through one of the new Vortex PST's at the hunting expo in Salt Lake City yesterday and I really had a hard time seeing the reticule on low setting. Any suggestions would be greatly appreciated.
