Best advice is to have a list of teams you want to tryout for and go to all of them. Don't let a team string you along and tell you" we like what we see but please come back next week". If they don't like what they see the first time, then the only thing is they want to see if they can find some one else that might be better, if not, they have you on a hook. If you get the call from a team you like, then stop looking and give them 100% of your time and effort!!!
