There are some aspects that you should consider:

- Having the right SkS so you can refresh Demo at 2s.
- Less GCD.
- BH/FC burst optimization.
- More direct crits (dmg with !!!) overall

Keep the first point. You'll need like 12xx SkS for demo refresh. Some say that you need 1283 SkS. I was below that number and now that I'm a bit higher than that, I don't see any difference. Sometimes and because of the battle odds, you'll be landing several gcds/ogcds with 0.5secs (more or less) of delay, and this will affect the right timing for demo refresh. For the 3 other points, choose a priority:

- SkS > DH > Crit > Det -> For speed priority.
- Crit > DH > SkS > Det -> For BH/FC burst priority.
- DH > Crit > SkS > Det -> For more direct crits overall.

Careful with gear choice since this define your materia.
Last but not less, careful with gcds/ogcds usage timing when you have to get far from target, since this affect the flow of your rotation -> optimal Demo refresh.
