Both products have a slick surface, and will protect your stick and floor.
We note three key differences: portability, and training area size, but the decision about which is best for your player is up to you!
Portability
The shooting pads are designed to be carried to a training spot, dropped down, and carried back somewhere else to store. Even a 6 year-old can do this.
The dryland tiles may be carried to and from an area, but are slightly heavier and require more effort to assemble, so most customers leave the tiles permanently in a training area.
2) Training size
The small pad is 24" x 48" which great for all aspects of a U10 player and shooters of all ages, but offers limited stickhandling range of motion for taller players.
In contrast, the tiles are expandable, so as players grow you can create a larger area.
Multiple pads can be placed near each other to create a larger surface, but there's no connection system.
