I don't think that the lawyer is the key, I think that the party seeking the custodianship is FAR more important. As an example, there is Lazar and he might own/control a ticker for 9 mos or more. He has many under his control right now.
Disanti seems to have a different MO, he doesn't locate the ticker first and then find the company that will accept it...he finds the company first and then find a ticker that meets their goal.
It's a big deal when you focus on the company instead of seeing how many tickers you can control.
It is that focus on the customer that sets Disanti apart. IMO
