Re: BG 4.0 vs Elemental Leg elastic
I have all 3 and never noticed a difference until I had a newbie. I tried (new - so leg elastic wasn't loose to begin with) BGEs on my daughter and she is just now fitting in them in the legs at 8 weeks. She has pretty chunky thighs too. The flips and 4.0s fit snugger in the legs so she was able to wear them a little sooner by maybe 2-3 weeks.
So there isn't much difference unless you have a newbie but they grow into them fast.
