Have you looked at the Ultra Stick 25e?

That would be a good 2nd plane IMO.  I dont have the 25e but do have the mini ultra stick and its a blast.  Just put floats on it to be my float plane since I have a 40 and 60 in GLOW power.

The stick fits 3 of the criteria brought up by people posting in this thread...

1.  Its High Wing
2.  Its a tail dragger
3.  Lands easy like a trainer.

Are you ready for a Stick?  Ask your instructor...sounds like you are in a good club, so I would think he could tell you if you can handle one or not.  The Stick can fly slow and land a lot like a trainer.</p>
