to all who replied, apart from the jokers towards the end there, thanks!

I spoke to a guy in a hobby shop who told me that he could not see why a CAP would be a problem - I guess that is why I went down the wrong road.
In one of the other second plane threads someone has recommended a U-Can-Do 3d as a second plane. I was totally surprised by this and would not have believed it except for the fact that one of the guys at the field who has one said the same thing last week. Is this a good second plane (obviously if you limit the throws at first)?
