Some use duffel bags, some over the shoulder bags, some luggage carriers on wheels, etc. It all comes down to what do you like.
I started with an over the shoulder bag which I really liked, but eventually got too much stuff and moved to a luggage carrier on wheels which I didn't care for. Now I use a wardrobe carrier on wheels and like it alot (albeit its heavy, but sturdy).
Many referee web sites or luggage sites (as below) can give you ideas. Good luck.

And, as Mbyron says - ask around and see what others use.
