try climbing under the screed of a paver to remove kick plates in a tube 16" deep with ZERO visibility and no room to use a flashlight with only a couple inches on either end of your ratchet.
You will appreciate the extra 6 points
Tight space is not an "excuse" to use a 12 point, it is a reason and it is not lazy to use a 12 pt socket on a 6 pt bolt either, it is convenience and makes a job easier to complete, meaning you can move onto the next project (or job) more quickly.
using 12 point sockets with a breaker bar helps a lot, with a 6 point socket there are always those occasions where you need the socket to grip the bolt at a point where a 6 point will not, to gain the leverage or room that your hands need to get enough swing to crack the nut loose.
This forum is full of great people who will be more than happy to help you with any questions you may have, trust me, but being stuck in a one track, generalized mind set isn't going to help anything. Come into it with an open mind and take all information offered in a positive manner and your time on Garage Journal will be a pleasant experience.
