My old volkl karmas, which were going to be perfect, unfortuneatly had a heel piece pull-out and are unusable now - except as wall art.  I don't want to completely destroy a pair of new octolands, so the only other candidate is a pair of volkl supersports.  They are 150's and not twin tips, but very soft.  I am wondering how important a raised tail would be if you're only skiing thin snow and pavement (where it shouldn't matter).   Thoughts?
