Out of those you mention, I have flown the Brio, Extreme Flight Extra, and a Mini Katana (they all belonged to a friend of mine). By far, the best is the Extreme Flite Extra. It flies the precision stuff a little better than the Brio, particularly knife-edge stuff. The Brio does not do 3D nearly as well as the Extra.

When I finish up some of my other projects, if there is any money left over I am going to get an EF Extra.

You will certainly be able to takeoff/land in a soccer field, but the over-flight area will need to be larger. If there are no trees in the way, you should be fine.
