Try http://www.marker.net/en/products/The-Griffon-Schizo-12 the Griffon Schizo. I go last yrs Griffons I am 180 lbs and they worked out good. At least with th schizo u can move them up or down 3cm either way to tweak you style...
Did u mean u will mount - 5 cm (back from center line 5 cm ? (powder / clssic mount)
don't mount -5 unless the vast majority of your time is spent charging(which is a bit wierd for using bents..). Mount +7ish(core center) to +8, and they will still be fine on anything and more stable(because of the shorter running surface, you are closer to the center of it). I rode bents at about +5 and about +7 and the +7 was much more enjoyable anywhere.
Oh, and get Tyrolias(Peaks or Mojos), or good Salomons(S914s/S912s/S916s), or FKS, not shit Griffons/jesters. They don't control bents well and suck. =)
