Professions for a rogueFollow

I did leatherworking skinning until I was level 375 each, then learned engineering to replace skinning. Its up to you how you want to proceed, probably a gathering/crafting mix would be the best choice though as with gathering and crafting you can use the low level mats you gather while levelling to level up the one profession (i.e. mining and engineering or leatherworking and skinning) then drop the gathering profession once you hit northrend and pick up a different profession. It really depends on how much money you want to spend and if you want to farm the mats yourself.
