Now that Kästle is making the MX88 in a shorter 173 size, it's on my radar. With the addition of tip rocker, will they still ski fairly long? I tried the MX84 last year in a 176cm on the same day as the 175cm Laser and they felt long. I am 5'11 190 and don't think the MX88 in a 180 would treat me well. Looking for the 88 with the Kästle bindings- who has the deals ?
