Figured this was vaguely interesting enough to warrant a new post, considering how I've written off Zeus's EG as not having enough LAD in any setup it's compatible with. I found a setup that does okay.
If you use Flame Pegasus' Metal Sharp CEW, the CEW provides LAD. The tip is like a wide flat section with a ball the size of FS's S part in the middle, all made of metal. It's not the most stable, but that's not a huge issue for it. The flat section has sloped edges, which provide LAD as the bey slowly topples, first with the tip and the edge touching the ground, and then with the edge and part of the blade base touching the ground. This means it can get in a couple extra rotations at the end of a battle, as the rotation of the CEW keeps the bey rotating slightly longer. It's also a pain to judge because even the lightest contact will make it spin again, so when the beys are right against each other at the end of a battle, it's hard to tell when it has stopped.
It's enough to do okay against this: (by okay, 50% or so, maybe more)
AR: Tiger Defenser
WD: Wide Defense
SG: Neo Left SG (Double Bearing Core)
SP: Defense Ring
BB: Customise Bearing Base (Burning Kerberous)
I used this setup:
AR: Tiger Defenser
WD: Wide Defense
SG: Right Customize Gear (Free Shaft Version)

CEW: Metal Sharp
I'm currently working out which bases work best, I've tried Zeus, Wolborg 4 (basically the same as Rock Bison), Metal Driger, Driger G and Draciel G. I've only got Dragoon G/GT's and Gaia Dragoon G's Bases that I haven't tried, as the spikes make them impractical for zombies, I have both Dranzer bases coming in the mail still, and don't have a Gigars or Deser Sphynxer.
Draciel G, Driger G, and Zeus seem to be the best so far. The first two seem to have better LAD than the other options (well, they interrupt the movement less when they "anchor" the bey as they scrape the ground), Zeus's isn't bad either.
Draciel G's reduces chance KO's against opposing zombies, and seems to be stable, but is KO bait for things like 10bBistool, Driger G's has good LAD and is harder to KO, still gets OS'd by 10bBistool, and Zeus's has slightly less LAD as far as I can tell, but provides much better defense against 10bBistool. All of them get OS'd by 10bBistool, Zeus seems to do better though. That said, most zombies don't do too well in the same spin direction as their opponents.
I'd avoid using Wolborg 4/Rock Bison's base as sit higher than other bases so the angles with the ground don't work well.
Of course, this isn't quite a top tier combo, methinks. For starters, it's locked in right spin, so it's only useful as a zombie against left spin opponents, which is primarily Defensive Zombies (which could KO it, but struggle to OS it), Other Stamina Zombies (50/50 so far) and Left Spin Attackers, which will KO it with ease. In right spin, 10bBistool OS's it quite reliably, so it's not so great, but yeah, most zombies rely on opposite spin anyway.
It also acts aggressively at the start of battles (due to the flat section of the tip), though steadier shooting would help a bit. It's not good for it to do that due to the low grip and weight of it.
Still, it's the best zombie I've come across for Zeus's SG, so yeah.
It could make it, of course, seeing as we listed Wing Cross, which is right-spin only, but it's a bit unconventional, and fitting the proper Shielded Ball bearings into Zeus's EG, at least for the top slot, can be a bit difficult, plus the parts aren't exactly common.
