FFP and SFP both have advantages and disadvantages.

As Brad mentioned, the reticle multiplier on the SFP PST mag ring is nice, and there are also detents at each multiplication setting, so you can be sure you are on the multiplication setting.

The advantage to FFP is your reticle is always subtended correctly, without any multiplication required.

The advantage to SFP is your reticle is much more visible on lower powers, where the FFP reticles get pretty tiny.

Ya after reading your review again Matt I am going the SFP route. Any thing I am shooting at longer ranges I will most likely be at the max magnification any how.

That is a nice feature to have!

As with any SFP scope, I'd still recommend testing & proving the marked 'ranging' mag setting against a matching true MOA or MRAD sized target at exactly 100yds. That is part of any scope shakedown I do, along with testing the graduations and repeatability of the turrets. If you are really going to rely on your reticle for holds, its a good idea to know at precisely where your mag ring needs to be for the reticle to subtend true. And as an overall quality assessment of a scope, its nice to prove a manufacturer's build tolerances are where they should be...

To be fair & accurate, the reticle subtension test must be done at a measured EXACT 100yards, not lasered range! Measured, with a marked string. After testing, one might be surprised to find that more than a few SFP reticles subtend true at slightly higher, or lower than, the factory labeled or stated true ranging power of the scope. Not a big deal to correct for, a quick Sharpie mark on the mag ring and you'll be G2G...
