I'm a mobile user, so can't see your siggy and how old your lo is... But, I would reconsider the Moby if your lo is still under 6 months. It is stretchy, but I've never had a problem with it stretching too much or feeling unsafe. My lo is 3 months and I plan to wear her in it through the summer before getting a beco Gemini for when she's older... Also, I just purchased the Moby as a shower gift for my friend yesterday, and it was on sale at target for 43, reg 54.
Not to hijack the thread, but you'll likely find yourself very uncomfortable wearing the Moby in the next couple of months. The stretchiness just doesn't provide enough support as LOs get heavier.
