Wolf mix dogs?

Anyone have any experience with these dogs? We are considering adopting 1 of 3 mixes. They are:

1) husky/Arctic wolf mix

2) Malamute/ Timberwolf mix

3) Shepherd/ Timberwolf mix

Can anyone give advice on these kinds of dogs? I've done a lot of research but I'd like to hear some personal stories because we have children and I've heard they can be a little unpredictable. Thank you!
