I have a 72cm DZ boy he's my precious Chaos. I love how he looks and the only problem I have with him is getting him to stand, I think this is due to the way his feet are. It seems he has a problem with having high arches? So he's difficult to stand barefoot, he doesn't give much warning when he falls, and often times I end up with a boy in my lap. I bought him second-hand of the marketplace here and all in all I must say I love him to death despite his little flaws. He's beautiful and when I can get him to pose, he poses really well. I usually have a prop or even his partner handy to help hold him up.
I don't have a 70cm but the 65cm body is the sturdiest of my crew. Stands like a rock, can hold smaller dolls up etc and fantastic at posing. A really good quality detailed body.
