Double pumper with automatic

I was doing some reading and a lot of books recommend not using a double pumper with an automatic transmission. I talked to my uncle who is a long time drag racer and he also said I should be running a vacuum secondary carburetor with my 727. He said a double pumper will be difficult to launch. Currently I have a 750 speed demon on the old 340 and the car hooks up and launches like a bear cat. I don't want to fix what's not broken in my opinion. Does anyone else run double pumpers with auto transmissions and have good success or am I just lucky?
