Yes, SB with the 183mm steerer were 934g, TB were 884g.
They are good at resisting brake-induced twist because of the large diameter blades and they're usually well aligned (unlike some road forks I've had).
I've used both and to me there is clear handling difference. TBs are more agile, a bit more sensitive and more racey. The normal ones feel more clunky and heavy duty.
