Harland Sharp "Original" vs. HD rockers
Both these are HS 1.65 ratio rockers.
Left is "Original"
Right is "HD/Heavy Duty"
Pictures kinda don't really do justice to how much beefier the HD's are. I'll try to weigh them and see weight difference.
Edit* not sure why first pic rotated but on that one, top is HD rocker.
