As far as the ladder itself, the biggest difference is the use of 100k psi steel vs. 80k psi in the normal ladders.  (Smeal aerials have been built this way for some time, and the tip loads reflect the difference).  Higher yield strength steel theoretically means you need less mass to achieve the same strength in an assembled ladder.  Since the ladder is lighter there are other advantages in the torque box design and stabilizers.  Remember though, it's all physics and there is no magic or cheating when it comes to weight and stability.  So don't be shocked when there are positions you can put an ascendant into that will be limited or not permitted by the software on the rig.  Personally, I'd want 4 outriggers and the 100k psi steel aerial, all parked on a set of tandems.  (Disclaimer:  I sell Smeal)  I wouldn't be surprised if pierce starts building the ascendant ladder on the traditional 4 outrigger torque box (or a variation of it) on a tandem axle chassis.

 

This is good info for me to know. My dept is planning on replacing our ladder truck in the next couple years.
