Which one? Extra-Ultimate-STA?
Not sure about the planes you have listed, but I would recommend the Lanier Edge 540. I have heard people say that it is the best, straightest plane they have flown and I agree. It is really nice to say the least. However, I don't think your 120 would be enough motor to do it justice. The Goldberg Ultimate ARF would be a great choice for your 120. I hade one of those with a Surpass 120 and it was a great combo. Have fun with whatever you decide on!
