Depends on the level of the kid. If you are talking top HS level, Flo at Frozen Ropes is getting amazing results. (High School Coaches send their kids to him.) Brandon at Premier has built up quite a track record having coached Josh Bell and Trevor Story. Gary Ledbetter at D-Bat Allen moved to town from California and has filled his plate fast as he is superb. All of these guys are hard to get into and have limited slots. Check out Flo's small group one hour lessons. Works more like Major League guys getting a few quality cuts then rotating, rather than sitting there for 30 minutes swinging and getting tired. All his kids can flat out rake.
