User blog comment:Backwardy/Should I cull the herd?/@comment-5215496-20121109031533

I have the exact same situation. I've been holding onto extra tier 3s hoping for a crystal trade-in but am running out of space. I have capacity for 42 dinos, so I know I'll need another habitat if I get them all, and even more as they continue to introduce new ones.

I'll hold out a few more weeks, I think. Then sell them. Since at level 52 I don't need more coins, it seems like a waste...

I'm not totally sold on the ghost versions yet...
