yes,but that is something that is happening in 12kg anyway, no matter how much power your spinner had, youll never get trough the likes of bonx or batterbot. And bonx was even 3 kilos underweight!

In contrast, feathers go up 13% which i admit is a lot. When the heavyweight limit went up it was 20% and none of us were worried about that. And ploughbot is powerfull enough to lift that extra 1.6kg, im sure.
