nrg20v

just thought i would ask anyone if they have or know someone who has fitted a lightened flywheel to a 4AGE 20 valve. My 20v is in desparate need of a new clutch and before i fit the new excedy HD clutch kit, i thought i might look in to fitting a Lightend flywheel at the same time. do the 20v's like a lighter flywheel? or does all drivability go out the door? I have had a quick look on the net what people have been putting in there toyota's, these are, TRD=TOMS, TODA, TILTON, QUATERMASTER and FIDANZA. Which one would be the best 4 price and quality? Also where is the best place to buy it? If any one could help me that would be great.
