Going back to the bag discussion, I tried a Zoot Triathlon bag last year. It was great for carrying a lot of stuff, but in practicality, it wasn't great for the track. The way it opened was kind of a clam shell design, so it took up a lot of space at the track - I guess tri people like things all spread out.
I ended up selling it and getting an Ogio Endurance 9.0, which is a duffel with backpack straps. I like it a lot.
