Certainly not an expert but...
Have you tried working on a single pump?
Do you throw a hand out as a counterweight when hand rolling?
Have you tried changing your body position relative to the boat?
I am a competent hand roller and, while I typically set up at near 90deg from my boat like a roll with a paddle, I find that it's easier to hand roll if you lean back towards your stern. I think EJ talked about this being best since it lowers your center of gravity, but don't quote me on that.
I would suggest trying different body/hand positions to see if it becomes easier. Good luck!
