I find it hard to believe that Tyros 2 styles sound better on a G70 because the G70 doesn't have anything that compares or even comes close to the Super Articulation sounds on a T2. Also going through the converting process, the styles rarely ever come close to the original.
Maybe someone could post an MP3 of the same style on a T2 then the G70 version playing it back, it would be nice to see this demonstrated
