I switched
My H376 came with the Dutchman Flaking system and like you I was not impressed. The Hunter manual came with procedures for adjusting the system but it just never worked as I expected. Then I noticed that newer Hunters built sometime after mine (1997) had gone back to the lazy jack system, I wonder why? I agree with Geo about lazy jacks, only if they are not installed correctly. Most riggers want to connect the system to the mast giving you a very narrow slot to raise the main and the battens will hang on the pulleys, even dead into the wind. I had my rigger install the system the way Hunter does, attach it to the upper spreaders, I have at least a 2 1/2 to 3 foot slot to raise the main instead of a slot the width of the mast, haven't hung a batten yet! It's also easier to remove the mainsail now when I need to. You just have to invest in redoing the sail cover.
