Drum vs Disc, Power vs non Power

Drums would be WAY more.

I can't agree especially in "today's world."

"How well" drum systems work depends entirely on the quality AND FIT of the shoes to the drums. The fact is that today, you can no longer buy proper drums for some of these old cars, in some cases you don't have much choice on performance lining, and most of "us" no longer have arcing machines, etc (thank Gawd, the dirty filthy things) -- to fit shoes to drums.

Last, disc technology, improved -- pad lining has moved forward where drum technology has not only stagnated but in some cases become unavailable.
