A few years ago I was trying to decide between those exact two rockers and decided to go with the Harland Sharps because the Pro Magnums (IIRC) were bushed. The Harland Sharps have been great so far, but be sure to look them over before you install them if you decide to go that direction. The ones that I bought had lots of shavings in the shaft and weren't cleaned up very well.
