Thank you for your email and positive comment about Inside College Volleyball.
You have presented a tough question - Tough because your daughter is getting good training and having a positive experience, but like all players, she wants to play more.
From a recruiting perspective, it is generally better to play. As she is going into her Junior year, she is entering the peak period of recruiting - Junior year is still dominant so it would be important to be seen, especially in SoCal as this is still considered the #1 recruiting region in the country (though Texas region players have a better reputation for being willing to play out of region). College coaches are going to be much more comfortable in their evaluation of her, and thus their recruiting efforts for her, if they have the opportunity to watch her competing in games.
As a family, if you feel you could gain similar training and a similar positive environment, and increase playing time, then I would jump to another club. This is all about your daughter, not the club - It is OK to be selfish when it comes to our kids, but selfish in a realistic way (too many VolleyParents are selfish in an unrealistic way with regards to playing time and talent of their child).
But, remember that the most important thing is that you are reaching out to college programs now and consistently moving forward - Don't wait for them to find you but get her digitally in front of them, so they know she is a great recruit.
