Went for a Dolan Seta this time.
Will see how this goes.

The frame alone is so much lighter than the Planet X which was circa 1.9kg!

My friends 56cm pre cursa is 1.8 something kg for just the frame, my 58cm seta is just shy of 1kg on the same scales.

My Seta frame is a 56cm and weights more than your 58cm Seta?

How does that work??
