10" or 11" Rear Drum Brakes?

I went with 10" x 2-1/2" B-body drums to go with my 73-76 front discs. (stock a-bod 10" drums were 1-3/4" wide through 1972) I tell people I basically have Road Runner brakes on my 68 cuda. The 70's a-bods and later F-bods also used them but by then the cars were heavier.
In my opinion, the 11" drums are overkill on an A-body and have you ever lifted one? Wow, they are heavy. That takes more power to accelerate them than a lighter 10" drum so your car will accelerate slower. Unless you are in some form of racing where you use the brakes a LOT....
A 73-76 A-body power disc brake master cylinder run manually works well.
