My $.02 .... I have and hunt with a Marlin "Guide" in 444 Marlin. I consider CDs type scopes advantageous for long range shooting ... 400 yards +/- and out. My opinion the 444 Marlin is not that gun. I would not pay extra for that feature. I use mine only in areas where I know shots will be 200-ish or less, and frankly most areas I hunt with this rifle the shots will be around 100 or so, or less. I have found bullet drop is easily manageable out to 200 yards without CDs. My scope is an older Leupold Vari--X III compact , 1.5-4 X 32mm with a German #4. Good luck.
