I've heard that some places still do it but I've never seen anyone in my area that does it. Not sure why.

Ages ago the spin balance was considered the most expensive way to have them balanced. Fewer folks paid the additional money and used the then bubble balance cheaper method. But with the newer computer balance machines they use similar but more acurate tire and wheel balancing off the car/ truck.
The real issue is the quality of drums and why the drums were out of balance. I bought a set of new rear drums from O Rielly's stamped made in Canada. One of the two started getting cherry red after short drives. That drum wasn't true on the inside and had to have it turned true before it solved my problem. Quality of aftermarket drums is the real issue.
