not really, just different. With a heavyweight, you can screw up and still spin the head back up. However, it comes down quicker so you tend to screw up more. With a low disk loading you can float it down and it's like everything is happening in slow motion,..lots of time to think. however, if you get the head too slow it can be difficult to spool it back up. It's one of those 6 of one, half dozen of the other scenarios,..they're just different.
