I've never used one, but about purchased one, you must realize your load needs to match almost to the T. Their reticle calculator fails to figure in elevation, or it did, I almost spent 1300.00 bucks on something I couldn't use, thankfully I had NF"s exball program. If Jupiter aligns with mars, and your load fits it in also, it will be sweet, no matter which one you get, but?
I have a friend who has a Ziess Z-plex 600, on a 7mm WSM hunting rig, and with his load, the reticle is deadnuts to 700, using the pillar at 700, like I said, it's sweet and quick.
If you're positive it will work, go for it, but if you're going to have to use it questioning things, and holding under, or over, it might be just as quick to dial your turret.
These reticles, when they work are a good as it gets, but any variance and it gets iffy.
I hope I didn't mess things up for you!
