What ladders do you like to use for aid intensive walls?

Hey everyone, I was wondering what aid ladders y'all like to use for those walls with lots of aid climbing. What do you like about them? What do you dislike about them? 

I'm looking to pick some ladders up for aid intensive routes and I was wondering what people are using. I've heard a lot of people like the yates big wall ladders, but I know others, like Yann from bliss climbing have other opinions.

I really like the aideer ladders. They are light weight, have a built in spreader bar and are really well made. 

Yates or Runout Customs both make fine ladders.  I can’t imagine doing an aid intensive wall with a ladder without the spreader bar, the bar makes it so much easier.  I’ve used the etrier style a lot also and will never go back to that style.  The only downside to the ladder style with spreader bar that I can think of is bulk and weight but your aid climbing, it’s all bulk and weight.  

I used a small section of thin pvc pipe to add a spreader bar to the metolius ladders.  It makes for a fully-functional-but-not-too-bulky solution.

As others have already said, a spreader bar is a must-have.

If I were designing an aid ladder from scratch, a design I would try would be making the top rung out of some kind of tubular webbing and putting a lower-profile spreader bar inside the webbing.

Edit: looks like the aideer ladders mentioned above have this feature.  Cool!

It sounds like the aideer ladders have dethroned the yates ladders in popularity, at least among those who have replied. I'll look into getting a pair. Thanks for the recommendations :)

Yates Speed ladders are by far the best. The Yates Bigwall ladders are top bulky with no real s vantage. 

What aid intensive wall you looking to get on?

I'm planning to eventually climb The Shield (and lead every pitch), and as a 5.8 climber, that means it'll be about 20-25 pitches of aid, depending on how things go.

Given how much praise the Aideers have gotten, I'm planning on ordering a set in a little while.

Those regular Metolius ones. Ill use any ladder except those offset step ones (like BD), I hate those.
