I'm forming an FLL team this year with 5th-graders. Being an AFOL and a Technic fan, I already have tons and tons of bits and pieces (beams, pins, blah, blah, blah). With that in mind, that sort of set should I buy for a FLL team? The NXT set from (...) (16 years ago, 12-Sep-08, to lugnet.robotics.nxt)
