SoccerPlus absolutely. DD is an ECNL keeper (2002) and has attended Soccerplus camps for 3 summers - 2 of which were NTC (national Training Camp in CA). Very intense and GK focused. This year I'm taking her to the New York camp, which was recommended last year by the Director (and also Tony before he passed). She has also done the ODP camp and it's no comparison as far as quality and development.
Another amazing thing about the Soccerplus camps is the camaraderie between players, keepers and coaching staff. My DD literally knows keepers from every club West of the Mississipi - keeps in touch with them and they go and support each other at national tournaments. DD always gets the response of 'how do you know that person' - and her reply is that she met them at a Soccerplus camp.
The NTC camp is very tough and intense. My DD still has scars (turf burn, cleating herself, being cleated, etc.) but also enjoys sharing the inside jokes about being a keeper with other keepers.
