i think you meant to say the silencer is a little wider overall. 80mm instead of the TM's 78mm waist. turning radius is pretty similar in the 178 silencer vs. 182 TM. TMs are a bit softer in the tail than the silencers, the tips flex pretty similarly though. i've skied my silencers one day so far, and really liked how they handled groomers mounted at +7.5. it doesnt feel as awkward as a lot of people have said it would.
