I'd no sooner recommend a set of procedures for this chap and his mates to fly as a group, than I would offer tips on the finer points of competition spin technique to one of his aerobatic mates - without meeting them, you have absolutely no idea of of the level of competence or otherwise of those in receipt of the advice.
I'm sure you've had an excellent time flying 'in company' with your mates - in fact, I'd bet money you've never had a negative experience in the process. Long may this continue. I'm happy that I've done my best to help the OP achieve his goal in a safe fashion, based on my experience, for what its worth.
