Out of those rockers, I vote Harland Sharp. I dont know much about the Hughes stuff, Im betting they are made by a similar company as the Indy stuff (Dove) but not sure.
I would look into T&D Machine. They might be priced close to the HS stuff and they will take the abuse of high spring loads.
What cam do you plan to run? And do you think the future will call for a upgrade.
Its cheaper to but the better rockers the first time, than buying two sets..
