My vote... Get an Ultra Stick and fly the daylights out of it. Great second plane, easy to fly, and will do most stunts as your flying progresses.
My personalidea for a 60 sized plane would be an Ultra Stick 40 with a 60 on it. That is still my every day flyer. I built mine with the quad flap option, which is hugely entertaining.
OKPR - you're a sick puppy - but it's a really fun idea.
How about a Great Planes Big Stick .60 with a 90 size 2-stroke or 4-stroke.
