I've heard and read so many mixed reviews on these two setups. People complain that spools are hard on tires, suspension, axles and then you've got others that complain that the lockers click and clunk and how annoying that is. But most people I've talked to that actually run spools in their cars on the street don't seem to mind them at all. I think that after reading these two posts, I'm just going to spool the thing! If I don't like it, I'm not going to be out much at least.
