For Have a Clue:
Like I previously stated in my initial post....you are the parents - it's not my place to say what's best for your family/daughter.
As for the "guest" player scenario - I still have the same points of view. To me, a team needs to win with what they started with - working together, growing throughout the year, etc. Picking up a "guest" player should be a last resort thing. If we all are really honest about it......I think we all know that's not the case! Teams are picking up "guest" players all the time to go and win specific tournaments. To me, that isn't winning a tournament the "right" way. That's my opinion - I'm sticking with it...
For 8494Player:
It's not about what other girls are doing either....as I stated parents can choose what they want for their families/daughters. However, people can and will have opinions about it (the ethics of it, the loyalty aspect of it, the perception of the family/player). You can't stop people from having opinions about it.
Personally I think...get on a team - stick with it - and try to go out and win with the team you chose. Seeing girls develop together as a team and then ultimately winning as a team is who I like to see win tournaments... NOT the teams who go get the best "guest" player to add on their roster at a integral time in their schedule.
As for the HS and travel ball scenario - I would venture to say that most serious softball players play HS softball and travel ball. This is a COMPLETELY separate scenario and alltogether different from adding "guest" players to go and win specific tournaments.
