I think that WOL has had more configurations than 4. Keep in mind that project-jk.com is an internet magazine and jk-forum is the magazine's co-business.
The writers/editors of JP Magazine have had their rigs go through several different builds to test a variety of aftermarket parts. Likewise, it makes sense that the self-employed owner of a JK specific internet magazine would go through several builds, do write-ups, test products, etc.
Shock length limits droop (unless you run limiting straps), and bumpstops limit stuff.
The length of the control arms on a JK are so much longer than on a TJ that they have less effect on flex/articulation.
On a TJ, if you ran shocks for a 4" lift or longer on short arms, the top of the control arm would hit the axle bracket before the shock fully extended.
On a JK, a shock designed to handle a 4"-5" lift can be fully extended to full droop with short arms.
On a JK or other vehicle, the amount of extended bumpstopping that is needed is determined by a combination of tire size, fender/flare clearance, and compressed shock lengths.

It depends on the lift height and the intended use.
For rock crawling in boulder fields with a lift of 4" or less, short arms are better because they provide more clearance and don't get hung up on the rocks.
For higher speed, desert running, a long arm is better due to improved handling, reduced dive, etc.
For street and highway driving, at 4"+, a long arm is more desirable.
On my 2 dr, I run a 3.5" suspension lift on 40s. It is my daily driver in town. I don't do high speed desert-type driving. What I enjoy are rocks and rock climbing. My skid plates and frame rails have deep rock grooves in several places. For this rig, a long arm would be a hindrance, reduce clearance, and cause me to get hung up on rocks more frequently.
On my wife's 4 dr, she has the equivalent of a 6" lift from Offroad Evolution Coilovers. Her rig has a Teraflex long arm and 37" tires. At 6", a short arm lift would handle poorly on the road and highway. It would be less stable offroad when climbing steep ledges and dry waterfalls. We go on family trips with her rig at freeway speeds. For her rig, a long arm was the best way to go.
So yes. Depending on the circumstances, I do argue for a short arm over a long arm.
There are some long arm designs that do not reduce clearance as much as others. I would be open to a long arm on my 2 dr that stretched my wheelbase back another 5" or so. Maybe a 3 link design with high clearance arms. This would help me on my steep rock ledge climbs.

Sir
The Rock Krawler 3.5" X Factor Mid Arm System is designed to be able to run 37's with only 3.5" of lift. We push the rear axle back one inch so you will not need to trim the pinch weld in the back to clear 37" tall tires. It is a rock solid system. It includes all the control arms, track bars and the lower control arms are all high clearance arms! It is backed by our abuse proof lifetime warranty.
On a 4 door at this lift height this system really seems to fit the bill over a long arm system. The extra wheel base really makes up for alot. On a 2 door, you will notice a big difference between a long arm and mid arm system.
Here is a link to the system if you are interested. Click Here!
Good Luck with your build..

lol, what is that, 4 lifts in 3 years...?
Rubi08, I feel ya man. On one hand people seem to agree that if ever there was a jeep where teh SA might be in the same league as teh LA, then the 4 door JK is it. on the other there does seem to be some consensus that the ride on the highway will be marginally improved with an LA. Even here though, some people seem to imply that if you are getting 8 flex arms then those plus the long wheel base of the 4door JK negates most of that "pro" for the LA.
Also, I have seen many posts of some very serious flex shots from SAs. One recent one that I will go dig up had a guy comparing pics of his OME HD flexed vs. his dads LA (I believe it was a 4" FT) and you couldn't tell which had more flex to save your life.
I just don't know...

In summary, I have found my FT long arm kit to be better in all respects to the short arms. I would highly recommend them to 4 doors with 4” and over lifts, and 2 doors with 3” and over lifts.

I can see that you might think that from mud country, but in the rocky west a few scratches on your lower control arms doesn't mean a thing. My control arms have groves cut in them about a 1/16" deep, but on an arm that is 1.75" in diameter it has absolutely no impact on strength or longevity.

The mud is the south where I'm from it's still about the rocks.
But I have seen plenty of guys hang up on their LA brackets. Now Saying that if I was going over 4" I would still get a LA kit, just not use it as a skid plate.
