DD is almost 10 months and the ones I use the most now are the Ultimate Baby Wrap and the Hip Hammock.
UBW is indeed stretchy but that's what makes it so comfortable. It's not a problem for me as long as you wrap it around yourself tight when you're putting it on before adding the baby. This one is great as long as you don't have to take baby in and out a lot (because it's a little cumbersome to get baby in/out and get on/off yourself). But it distributes weight really, really well and I've found it very comfortable for long periods. It's also very versatile, with lots of positions.
The one I use more often is the Hip Hammock. It's really easy and quick to get on and is perfect for quick trips down to the car, into the store, and any time you need to get baby in and out quick. I wouldn't want to wear it for a long time because it kind of hurts my shoulder. But I'm totally willing to trade that for how easy it is to use.
