Galarian Corsola IV help!

Hi all!

I just wanted to ask for your help! I am completely new to competitive-battling and breeding.

I am breeding a Galarian Corsola (Cursed Body) with a Calm nature. It's item is Eviolite. The moveset is as follows:
- Haze
- Night Shade
- Strength Sap
- Will-O-Wisp

I wanted to ask which IVs would be better for my Corsola going forward?

HP: Best
Attack: Best
Defense: Pretty good
Sp. Atk: Best
Sp. Def: Best
Speed: Decent

HP: Best

Thanks in advance!
