Creating a Brand Split

On my WCW save I finally have a TV Deal for Thunder in December and my plan is to create a Brand Split for January 2002.

I just wondered if there's a good way to book it / like angles where Authority do a draft pick / I can't seem to find one? Is it just a case of creating the angle myself?

Also i've never played a save with a Brand Split before - is there any do's and don'ts for playing it like this?

My initial plan is:
Starrcade 2001 - Piper d. Bischoff (on going feud for months, Piper winning causes them to own each brand)

Piper = WCW Nitro
Bischoff = NWO (New Wrestling Order) Thunder

4 PPVs a year WCW
4 PPVs a year NWO
4 PPVs a year Unbranded

Any tips for those who've played saves with brand splits are welcome!

- How often do you redraft?
- Do workers morale get worse only doing 1 show a week or 1 PPV every 2 months?
- Does a brand split affect any ratings differently compared to no brand split?

Thanks!
