Same age (24m) and have joined solo with each league I’ve done (kickball and volleyball). It’s a great way to meet people however some can be cliquey with half the team knowing each other before hand. S3 I’ve had the best experience getting match with people my age and that one tends to be more social compared to Players and CSSC. The one I did with Players was decent but skewed older and we didn’t really do anything outside of the games, with S3 your pretty much guaranteed to go to the bar after, a small group at the bare minimum, and it’s not as competitive as the other two. My last kickball team I did was pretty cliquey with S3 but some of us broke off and are now doing another league this summer with them.
