RE: 60 size ARF
The Stick (doesn't matter which one) and the many derivatives (The Pulse is one, as is the Easy Sport) can't be beat for a second plane. It's as forgiving as your trainer, much better in the wind, and can be as wild as you want it to be based on how you set it up. I have the H9 Ultra Stick and started with a .61 on it. It was sporty and could do pretty much any maneuver I wanted, but it wouldn't do a huge 500 foot loop so I put a .90 on it. And when you advance to fancier or more demanding planes, you'll still want to pull out your trusty Stick from time to time and just burn holes in the sky, especially on the gusty 30 mph wind days.
