As for "hurt your arm" no more so than a club can do already. People
already have crappy follow through a lot of the time.

I sure did. Always tended to bend my elbows, instead of rotate at the
shoulders. I think a Rolex would have helped.

How about... place the explosive charge on the *back* side of the club
head, so that the head is driven into the ball.
Just as (un) likely to "hurt" your arm.

Combining an explosive charge with inertial guidance would let golfers
concentrate on style.
