The "B" is more than suitable for you. Any differences are pretty minor between them. As for the "bits", you could make longer leaders (most do) or make add ons for what you have. Yes the "B" comes with leaders, but again, most of us make longer ones. Sharpies can be used to create your own personal color code for the lines. Tops, bottoms, lefts, or rights, whatever you decide on. keeps your set up straight. I can speak to the no-snag mod - works wonderfully. But 2 things - don't bugger up the caps as you remove the rings, and watch for the NASTY BURR under the vinyl cap.
Oh, if the kite comes with 2+3 wrap frames - all good. Learn on the 3 wrap and try the 2 wrap in lower winds!
Best of luck!
