The SYSCA u12 league is the only avenue for clubs to qualify for 13U Challenge, so U12 should be fine for all clubs. I had assumed most clubs would have one team in the new CPL and the rest in SCYSA, but am not certain. The rumor I heard was that the Battery U8-U12 would also play some of the same CPL festival-style games against the clubs not in CPL, including youth programs at other MLS/USL clubs.
