Decision #1: Does she want to play ECNL vs DA? (the play HS or not question). If her projected high school has a good team/coach, I would strongly consider ECNL (for girls only) over DA.
Decision #2: Does she like the experience of the pre-DA/ECNL team? (Players, coaches, parents, etc).
If yes to #2, then I'd go to that team ASAP. Consider it a long try-out, playing on the "Pre" team. Just talk to the club DOC to ensure that the coach you'd be playing for is the one who will be coaching. My son's SCDSL team was better than the team that DA coach had but we played on the team coached by the DA coach so that when it came to trying out, he had a spot to lose rather than had to have a great 2-3 days of trials.
I assume the end goal is college... the reality is for boys, DA gets more looks and for girls, ECNL gets more looks. Before Randy's Rebels' parents go nuts, yes there are anomaly teams based on grouping hired guns and finding a good coach that get into showcase and key tourneys... but if your club or coach isn't well-connected to your kid's top 5 schools, then yes, a DA or ECNL option is going to get your kid playing in front of the most college coaches and typically against/with the top players.
I do think as GKs, we could also play on a non-DA/ECNL team but be trained by a high capacity trainer who ensures strong/consistent development then use ID camps to get in front of our desired schools. If it's a mid D1, D2 or D3 level school, I am of the opinion that path will work. If you are wanting to play at the highest tier of D1, you will have to be able to explain why your kid isn't DA boys/ECNL girls. Not a deal breaker, but definitely will come up. Take UCI... they're about half DA, right now. It's just easier for a coach to go to a showcase and watch a dozen games with all college potential athletes than scout a HS game. Easier... not impossible. The benefit of HS is that it most reflects the college experience in that you have a wide variety of ages on the pitch together. So, the benefit of HS is it shows how a younger player performs with older players. But again, if your high school team is poorly coached, I would be a hard pass.
So, if your kids loves playing with a non-DA team, then I would keep her on that team and supplement with the highest quality keeper training, you can find... regardless of whether or not your club provides.
If your kid loves playing on the DA/ECNL team, go that route.
End of the day, if your kid isn't happy, the level doesn't matter... they will inevitably burn out. If they are happy, they will do the work to succeed at whatever level they enjoy.
My theory is our role as parent is to provide our kid the opportunity to play at whatever level they can and they enjoy. Then we challenge them to be the best at that level. I only push my kid when he/she gets lazy for the sake of lazy... or, if he/she is phoning it in/not giving their best. Otherwise, by 12... the drive has to be internal from them or burn out is inevitable.
