2way will have 1 team with no more than 20 which will allow max playing time. Teams that carry more than that benefit the directors only. Look for teams where player development is important and playing time is crucial.
Being in high school and on a B team for one of the local clubs is pointless. B teams usually cost the same as the A team but you get weaker coaches, inferior practices and most importantly, no college coaches are looking at B teams.
B teams are okay for younger grades when kids are learning the game. But for kids wanting to get recruited for college lacrosse, B teams are a waste of money.
