Replying to Will Salomon Impact 8's be good for me?

I need a new boot for NZ, will mostly be doing park, and a bit of charging powder when there are some dumps. Went to a bootfitter and he suggests the Salomon Impact 8's (they have a flex of 90). I really want to try some freestyle specific boots like the SPKs or Rossi SAS's but there doesn't seem to be any stockists here (Australia). Would the impact 8s be a good boot for me? or would something like an spk's be a lot better? I get really bad shinbang in my current 1080s - they are really old and really packed out.

I'm 6 foot 162 pounds (73kg).

oh and yeh.. i've tried on FTs, they don't fit me well.
