Are you going to the Australian Zoo? The one Steve Irwin the "crock hunter" was buried in? I was a bit of a fan, even though he was a nut. I'd go for sure if i were in your shoes.

I could not decide on a tiger or M41 either, ended up buying both in the "super" versions from Mato toys. I ended up getting metal tracks for the tiger, but they made it slow and very heavy. My M41 now runs circles around it. Love them both though..........
