You will still use the lower power to open up your field of view at any point needed, but the reticle will appear smaller on an FFP because the POI never changes. I have Hawke Sidewinder 6-24x56 FFP and an Aztec Emerald 6-25x56 FFP plus Hawke 8-32x56 AirMax SFP scopes. Honestly, and after shooting tens of thousands of pellets through each at this point, I don't really have a preference. The 2nd focal plane reticle is easier to see when shooting out really long distances but I really like the convenience of having the POIs always consistent with the reticle that the FFP offers, and rarely (never to date because of my set-up) have an opportunity to shoot beyond 100 yards, so reticle size is not an issue for me....
