I've only recently gotten my first lightweight flywheel car on the road-a 351 Cleveland powered '69 Cougar.  Stock cast iron flywheel was 28.6 lbs and AL is 13.8 but I still have a cast iron crankshafts, 8 steel rods, 8 pistons, and a big  OEM cast iron harmonic balancer.  It didn't make a huge difference in my yet limited experience with it.  I see no degradation of driveability or difficulty driving it.  I also haven't seen a huge change in how the motor responds to throttle inputs.  I say go for it.
