If it were me, i would opt for the CDS dial. However, i would hold off for awhile, before i ordered the free engraved for your ammo dial.

My old 4X, and old vari-x III, i sent to Leupold to install a CDS dial. Cost was $60 each, and has made my shooting adventures quite a lot more fun. The engraved dials allow one to range the target, then twist the dial, and be good for elevation. For me this results in fun, and meat in the freezer.

Playing around with the generic moa dial is fun too. One needs the MV, the data for the bullet, a ballistic calculator, a range finder, and the rifle sighted in with the dial at zero. From there, one can twist the dial whatever the calculator say for the range, and have the bullets impact whatever the target is. Great fun! Great fun to burst a pop can at 1/4 mile with the very first shot, using the simple moa dial twisted up, by using what you know, and mathematics.

For hunting it is best to have enough practice, and a dial engraved for your load.
