Currently building up a TF Dart too and it doesn't feel heavy at all. Oversized tubing and all. Convinced myself not to go into weights and all that on this one though.
Even with that frame weight, it's not impossible to get it to around a respectful 8.5kg (using run-of-the-mill component and such).
