2014 Alpha X are quite still. Stiffer than the Alpha 1s from '13. I had the '13 model and found that they were great and all but a little too narrow. I got myself the Halo 2s, same sidecut as the Alpha X, but softer. Softer than the Halos from '13. I much rather the wider underfoot (95 compared to 83), riding all mountain with a wider underfoot makes it much better for shredding through crud and with the rockered profile, they are amazing in the park. I ride 95% park with my halos and love it! When it snows less than 10cm I'll still grab them and they can handle the snow, even when it's in the park.
Hope this helps. Don't know what's in store for '15, but if you can get them for cheap, you'll probably love them!
