Not necessarily, that's one thing I like about the Trijicon is in the bottom of the view it has the correction at different magnifications, so 1@16X, 1.5@12X, 2@8X, and 4@4X. While not as ideal as FFP, it's not hard to just leave it on 8 and know that the subtentions are double. I've been trying to convince myself to make the switch to MILs and FFP because I know it's cleaner, but I'm just not in love with what's available. Will probably try to snag a Maven RS1.2 if they go in stock, but the only other option I like is NF 4.5-14SHV. If Trijicon made a Credo with the center dot reticle in 2.5-15 or 4-16 in FFP I think they'd sell a ton.If you need to make fast wind calls and hold for it, a SFP variable is not the way to be successful. The SFP reticles are only valid at the top magnification. That means you have to adjust your scope to use the reticle and find the target at high magnification before you can aim and fire. FFP or a fixed 6 will beat that every time.
