uhh...

what do you want with a low polycount? are you making for a game or do you have low hardware specs?

trying to reduce your polycount by turning stuff into sub divisions... that's.... umm... odd?
when you turn an object from poly to NURBS or sub-d it no longer counts towards the polycount because it's no longer made of polygons

sub-ds are infinately curved like NURBS so it'll always be smooth
but you can make polygons fake the smooth by softening the normals.

the problem could be with the bottom of your trophy
