LOVED my Moby, but sometimes I found it hard to tie because it didn't seem long enough and I wouldn't consider myself plus sized--so you might need to look at a wrap that is longer?? I am short--5'3" and about 140 when not pg and it seemed not long enough for me. I made myself a mei tai when ds3 was 5 months old and I love it too. I made the straps nice and long so it fit well. We still use it all the time and he just turned 18 months. I usually carry him on my back though.
