Since it is possible to skin using a macro on an alt, I set one of my alt Shamans to skin. Since I use Gatherer, I plan on going Mining/Herb on my main.

Solusaa: Alch/Jewelcrafting
Solusab: Alch/Tailoring
Solusag: Tailoring/Enchanting
Solusad: Skinning/LW
Solusao: Mining/Herb

My 70 Rogue is already a Miner/Engineer and Shamans do not acquire much from BS that isn't BoP, so I was more interested in covering most profs.

Two Tailors and two Alchs will grant me access to a couple of cooldowns per set for cash, though I may go Alch/Ench on Solusag.
