there were a lot of LWFs out there that weren't balanced well in the first place (fidanza comes to mind). the aascos are supposed to be balanced very well. one could always take it to a machine shop and have it checked prior to installation.

as for the dual mass flywheel? jake is right that just swapping to a single mass removes the elastomer damper from the engine / driveline interface. most cars use a sprung centered clutch disk rather than a sprung centered flywheel. when i installed my LWF, i had a spring centered clutch made for my by Spec. this protects the driveline / motor from excessive shocks.

one wierd problem some of the 997 GT3 guys have experienced, and i can't really figure out why, is that when they go to a LWF, their crankshaft pulley unscrews and essentially falls off the car. not a problem on the boxster.
