new halo kicks ass cuz its wider. feels more substantial than the older narrower build. its soft and easy to turn, but still stiffer than the al dente, which is just a whole different feeling of soft. 178 felt like a short small jib ski, not for a fast all mountain skier or a big jump skier, unless you are very small. 188 felt more like what a soft 183ish mid fat park ski would feel like. easy ski for its size.
i would say halo II for a more normal ski feel. al dente if you just want something totally off the wall different from what normal park skis feel like. some may like it. some may not.
