I got Powder Pros for Christmass, love them, they are so much better in the powder.
I honestly think some people expect too much from them though, these skis are designed for Powder, I don't think you can get a ski that is perfect for bolth powder and trails, they will either be excelent for one or the other, or ok for bolth. The powder Pros do require more stearing effort on trails and do dart more but the are amazing inthe powder where they belong.
I also wonder if people are setting up thier sled right for them, you want minimul ski pressure and you want them to be mounted in the forward holes (moving the ski more forward) this puts more weight on the rear of the ski and carbide (less stearing effort, more darting but best for powder riding).
