The LRD's are adjustable. You can set it for top bottom or middle. Being in the middle is about the right combonation of power at the bottom and still have some top end spunk. I have a LRD on my Blaster and I can lift the tires off the ground easy in the first three gears with no clutch. I don't know about the FMF.
