Take a look at Rossignol Jibsaw or Retox. The jibsaw is a little stiffer but has magnetraction which will help on the hardpack and ice. The retox is softer. Both have blunted tips and sintered bases. The jibsaw can be had for around 320 and the retox for 280-290
Edit: They arent flat between the bindings. They both have amptek which is cambered in the middle with rockered tips.
