I use the NMRA weights in HO. I have also found that when there are problems, it's not the absolute weight, but combinations of light and heavy cars in one train. That, or putting light cars or just too many cars around too-tight curves.
There were studies in the model magazines back in the 1950s that concluded (possibly correctly) that the biggest factor in car weight performance was CONSISTENT car weight. As Bruce says, mixing heavier and lighter cars can bite you. I think one could very probably choose a weight below the NMRA weight now recommended, but the key would be, again, to STICK to that weight and get as close as you can with every car.
I continue to use the NMRA weight, but then again, I don't have any heavy grades that can hurt locomotive performance.
