To be honest, its not any different from any other bonding. Any bonding can be easy, or tough, it depends on the personalities.
I currently have a trio with two ladies and a man, and the ladies were bonded first, and I had a trio that was two ladies and a man (one of the ladies died in June), and both ladies were dominant, but because neither was particularly feisty (they both just thought they were Queen) they figured it out without fights (just some chasing), and became really, really close friends.
I also had a quad that was three girlies and a guy. It did disband when one girlie got ill but whilst that bond was a challenge, it was doable.
Just be ready and prepared with a variety of different strategies so that if something fails first time round then you have other options to try.
