Question about changing stats on Zodiac

Hi.
I am close to the end for my Zodiac weapon: some dungeons, 2500 sol, then I am done. But the secondary stats on my nexus are not that nice, so I would like to change them. I heard it is still possible to change them once we have the Zodiac. But I also heard the sphere scroll we have to do is a new one (novus and nexus were sharing the same sphere scroll. Zodiac has its own). My question is the following: how many materia slots do we have to fill for this new scroll? Is it still 75 like Novus/Nexus (and then there is a scaling) or is it more? It is important for me to know, because the materias I want to change are really expensive...
Thanks!

Still 75. The game will scale up the stats where appropriate for the higher-tiers of the relic, and will show a preview of them before you commit to the new changes on your weapon.

Hi.
Thanks for the reply.
That's really nice. Furthermore, it seems it is possible to use the round numbers to optimize the weapon.
