That makes sense. I just have a 1.3 colony, but I always like to save money. And you've just confirmed what I've been thinking about the wheel; It needs to go. I've had my ASFs for three weeks and they are absolutely obsessed with the wheel. Every time I go in to check on them (and I do mean every time) they are all four playing on the wheel together. I told my wife "I don't think we'll ever get babies because they can't stay off that wheel long enough."
Thanks for all the info.
