I think you will all find that I am Sig's designated cake carrier having previous experience last summer. I would even go as far in saying that I would empty the entire contents of my bag at HPC to ensure I have enough room. The only drawback is having to share it out, last year I was fortunate that everyone forgot it was in my bag so, unsure of the best before date and taking no chances, I scoffed the lot on the train home.
