RE: bip as a second plane?
The tiger moth is definetly one of the more gentle bipes out there. I have a pitts and it can be a bear landing it sometimes. I don't think the tiger moth has any of the nasty snap habits like the ultimates. There are much better choices for a second plane. It is your choice in the end though. If you are proficient on your trainer, and dead set on a bipe, that would probably be the best one.
