Mass is the same, ~3285g with an STH2 16 WTR per ski. I think it is more a factor of the reduced contact length (more rocker at both ends). The older 188 would generate some tip flap at speed (past the Titanal DRT layer) but it still felt rock solid. The new ski doesn't do that (metal goes all the way to the tip around the perimeter), but it does "wander" a bit on firmer or chunkier snow. Noticeable on the hard snow at the WWSRA testing venue, never entered my mind last week in Utah.
