I don't think what any of us would do really matters, does it?. Do what works best for you. You have enough experience to know that when you see it. If you think you would like to ride with the group, maybe try it for a while and see if it is working for you. If so, stay with them. If not, drop them or let them drop you.
Whatever you do, have a great ride and post lots of pictures.
