I picked up a 143 version of the Power Arc to try out. I'm partial to curvy saddles so liked the shape right away. Set up and feel is similar to my current SMP Dynamic. Running the nose 4 degrees down (a little less than 1deg up from the center of the seat). Setback -1.5cm from the SMP put my hips in the same location. Expected with a shorter saddle. I'm used to feeling locked in, but felt a little more freedom of movement fore/aft than the Dynamic.

Spent a couple hours on it w/o any soreness or pressure. TBD if it gets at the slight instability I sometimes feel with the Dynamic.

As an aside I have an extra seat post that I keep around for saddle auditions. Makes it very easy to switch back to your A setup. If you like to tinker with fit this is a great way to try out different saddles.
