Yep, in my case I have two '05 females. One is a ferocious eater and is over 1200g(could be bigger I'm sure), and the other is around 450g? I think. The second girl is very shy and will only eat one mouse per week.

My '06 babies range from 200g-700g. One August 2006 boy(my Lemon pastel) is almost 700g and a fatty. Hasn't missed a meal yet.
