I purchased the brake pads I believe off of formymercedes.com they were 260 shipped? This will be my first experience with the new pads as well as the zimmerman rotors. Look early to mid week, next week as I will have a full report on the combination.

they have Curved vanes... why should the cross drilled have straight vaines? The rears have no vains as they are a solid rotor

I knew the vanes... "chanell" cold air in to the rotor to cool but what I dont understand and maybe you can explain this, why wouldnt the drill patterns go along the same path

I think the vanes/channels on that diagram are all screwed up the left is for the right and vice verse. The direction of the slots/vanes are suppose to be leading out not in.
And remember Pete there is a 500 mile break in period that you should strictly adhere too. To extended the life of you pads and rotors and to prevent squealing!!! Be very light and gentle no hard stops!

Example is the PF 2 piece floating rotors I bought for my old Evo 8. The dimple slots follow the vanes pattern. Please ignore the hand. It's not meant for anyone in this forum.
and the one I showed is a Stoptech rotor which have the pattern of the slots goes in the opposite.
I would've chosen slotted or dimpled over cross drilled if I was shopping around for rotors due to crack stress that cross drilled have created in the long run. But since we all drive our MLs on the street and will never see the track, majority of us will be fine in this case.
and also, FWIW, cooling vanes are to extract heat out of the rotor, not feeding cold air into the rotor. You can most certainly take advantage of this specially on a race car by putting in cold air ducts pointing directly to the caliper.

After installing new brake pads, make 6 to 10 stops from approximately 30-35 mph applying moderate pressure.
Make an additional 2 to 3 hard stops from approximately 40 to 45 mph.
DO NOT DRAG BRAKES!
Allow 15 minutes for brake system to cool down.
After step 4 your new brake pads are ready for use.
