fly,
You just mentioned flying helis, which may make a difference in your learning curve. How did you take to the transition from Helis to fixed wing? You MAY just have the reflexes to fly that RV-6.

I'd still highly recommend a decent "second" plane, and the Tiger 2 is a good one. You also just might want to look at the World Models T-34 Mentor. It's being touted on RCU as being a very forgiving plane, and many feel comfortable recommending it as a "second" plane.

That just might kill 2 'birds' with one stone. Your warbird and preparation for the RV-6.
