Always play where the coaching and competition is better. If she was a pitcher, she would want more circle time to develop, and being the number 4 on V wouldn't help so JV would probably be best. But as a position player, you should remind her that as a sophomore she can begin earning that...
We like the longer barrel length composite bats such as Easton. My daughter swings a 30 -12 now is a contact hitter, not a power hitter. Bats that seem like they would be her fit are the Easton S series and Mako, LVS Xeno and DeMarini CF8. Any feedback here would be appreciated greatly.
