What size is the most popular Speedy

Based on conversations with SA's at two stores, the 35 has spiked recently in gaining popularity. I love both but tend to lean toward bigger bags. I am 5'5" and carry a 35.
 
Thank you everyone, I will be going to LV store within the next couple of weeks to have a look at a 30 & 35. I just hope they have them in stock, I will post pics of my new Baby when I get her lol
