I may be in the minority here but I vote for the Siena. I currently have a speedy b 30 and am leaning towards selling it for a Siena pm. The speedy is a little too large for my frame but I find that it gets heavy because I use it with an organizer. Also it sticks out causing me to bump it into things often. I like that the Siena has a wider opening and looks good with casual clothing but can also be dressed up.
