I also loot with my main.

i find mailing things helps keep things organized if you have all toons with different professions.

I Send all cloth to toon A and all ore to toon b and all BoE to toon c, etc). as well as clears up inventory space for all until you have the time to actually use the stuff. plus you can do 15 ( i think?) at a time than having to trade 6 at a time. With guild perks, it's also instance and you can do it when you need to inside instances, etc.
