I have heard, many times, that the only difference between the red AAs and the Gray Handicaps, is the color. But, I get at least 3 reloads from the reds before I see splits, and 5 from the Handicaps. I check them carefully, and find the Handicaps load longer.
Some reds give me 5-7 loads, some Handicaps 6-8. But, the reds split quicker, and the Handicaps load longer.
Really seems there must be a difference besides the colors.
