Consider these and you will have your own answer:
Hitting the ball is prohibited.
How much power do you really need to put the ball on your team mate's stick?
Do you play with a wood or composite stick on the field?
Why change your style indoors?

Yes, there is a switch toward composite. However, the indoor game does not require as much power. Considering the small format of the indoor court, a powerful stick can be more of a problem than wood.
