Sometimes the problem with dilution H is that people use it in tanks that are too small to ensure there is enough developer concentrate in there to avoid developer exhaustion.
Based on Kodak's capacity recommendations, you should have at least 378 ml of dilution H in your tank for every 120/135-36 roll.
I've had good results from Jason Brunner's 1+ 49 dilution for HC-110, which is effectively the same as dilution E (1 + 47). You can find more info here:
