I've got two Troy MRF-DI (M4) and they are rock-solid. Can't beat it for the money, and the QD sockets are perfect. Highly recommended!:D

I got the Troy, it will not move at all.
Per a post from Joe Marler at TOS the DD EZ is 2.4" wide - plumper than I would care to try.
No idea on dimentions but here is a shot of a Troy MRF-DI

How pronounced of an oval shape are you looking for? Drop in rail widths are pretty limited I believe, compared to FF rails.
The height of any rail will be locked in at the height of the upper receiver. This only leaves room for variations in the width of the side rails and lower rail. With drop-in rails, width wise, you really cant get any thinner than the diameter of the D-ring. There's a little working room there for variation.
This leaves the lower rail and how far it can hang down.
The KAC RAS I have measures 2.29” high, rail outer surface to outer surface. Width comes in at 2.18”, rail outer surface to outer surface.
For quality verses price, I think these RAS Seconds are a hard deal to beat, and they would be my recommendation. I’m glad I was alerted to them when I was shopping for a new, better quality rail system.
I'm with Quib on getting a KAC RAS at that price point. I got mine new for $145 a few years back.
I think your best bet is going to be the Ergo Z Rail. Unfortunately, I couldn't find the dimensions for it, but if you look at this thread over at Weapon Evolution, you can see it has a very, very oval profile, much more so than any of the other systems (except for the DD Omega, which I still think you should strongly consider). According to this thread, the Ergo rail has the same dimensions as the Omega.
Here's some info I gathered on the net about the widths of other rails to help you decide:
DD Omega - 1.9"
VLTOR CASV-M - 2.12"
KAC RAS - 2.18"
MI MCTAR 17 - 2.45"
