You need to decide what makes sense for your situation, but clipping them so you can take them around like a dog will not work. I used to clip Gilligan to keep him from flying on the Macaw's play stand where he could be killed with one bite. It worked for a while, but then he learned to fly even with the full 5 feather cut on each wing, and since he less control, the odds of him making an emergency landing on next to the Macaw went up. So he is fully flighted again. He does not fly often, mostly when spooked. Also, I never leave the room without locking him up or taking him with me because he will come looking for me and then I have to find him.
Clipped or not, treat your bird as an escape artist. They can be gone in a flash. That is how I got Gilligan, he escaped from his previous owner and wound up in tree in front of my house. I never could find the previous owner.
