The trick is apparently some will do it and others won't.
The 20.5 lbs feels closer to the stock clutch, from what I understand this one eliminates any chattering at idle due to the extra mass maintaining some load on the teeth of the flywheel gear and stopping the backlash chatter.
Both offer more holding power than stock. When I get around to doing the clutch I'll go with the 20.5 pounder as I don't want to take the punt that my car might start making the random chattering noises at idle just after I've spent all that money on a new piece of kit.
