Sfp make sens when you are using your turrets for wind age and elevation. You can dial up and hold for the wind , but that starts to become a bit random when you hunt different style and sizes of animal . Where I see a disadvantage with sfp, is when you do not dial up and only use a hold over reticle that only works for one magnification. Quite often it is at the highest magnification. And that does not work well on two occasions: when there is heavy mirage and when close to the hours of darkness. In both cases you have to dial down the magnification which throw away the hold over graduation the scope was originally set up for. Of course you can practice ( a lot) and stick all kind of reminders on your butt stock, but one day or another if you have to rush a shot that will turn into a miss.
Where the ffp shines is for hold over with the reticle. You can not stuff the magnification either you hold for wind or elevation or both.
I understand the complaint of some regarding certain reticles covering a good portion of the target. But the scope industry is evolving and there are now some reticles with more clever designs which resolve that problem.
At high magnification they are very fine in the middle. At low magnification the outside posts become thicker but still leaving a good opening on the middle.
This nightforce one is a good exemple of what can be achieved. I just wish it was available on higher magnification scopes:
The Burris veracity reticle is another reticle that went in the right direction:

If the scope is not illuminated, then the thick post at lower magnification are definitely an advantage when hunting close to the hours of darkness. First because you can see the reticle, and second because you should not risk taking a shot at long distance ,therefore if you take a shot at an animal below a 100yrds , even at a lower magnification you will not cover the animal and the thick post will still allow you to " bracket" the body of the animal.
With an illuminated reticle, that does not present a problem any more, as you can simply put the red dot on the body of the animal at any magnification that you see fit for the purpose.
