Well... If you think about it, SSJ is the best choice. If youre able to control your KI as much as to go SSJ, you could easily learn to get the beams. After that you could easily learn to fly... You could practice and become SSJ2, 3, heck for the hell of it 4 even. And youre SO fast when your SSJ/2/3/4 that you wouldnt need instant trasmission because youd just zoom your way to wherever. Besides, I bet you could always learn to do it if youve reached that level. Plus, fusion is just a dance. You could learn, if you wanted too, teach it to yourself.
SSJ for me.
