agree that Patrols are metric - there are AF equivalents, eg 14mm = 9/16, 16mm = 5/8, 19mm = 3/4.
works less well at the smaller end of the scale - some 3/8 don't like 10mm, and 1/2 can be too big for 12 sometimes, and 13 a bit sloppy
Sometimes an old AF spanner can make up a gap in a new set of metrics - for instance metric kits sometimes omit 16mm for some reason.
And, if you've already got an AF set lying around, and acquire a metric set, you end up with quite a few that are the same si2e, which can be handy for undoing a bolt fastened by the same si2e nut (as opposed to a nutsert or threaded hole or whatever)
Bubba, if you don't spend a lot of time with a spanner in your hands, or down at the gym, or otherwise developing hand arm and upper body strength, a set of long ring spanners, or a breaker bar for your sockets can make a big difference. I climbed under Silver a while ago to undo the plugs throughout the transmission. Couldn't get any of them to move, even with a breaker bar. No room to move, and very awkward. Took it to the mechanic, who put it up on the hoist, and easily cracked them all with the same si2ed breaker bar - he does that kind of stuff all day, and is probably stronger, and could use his body weight and position to crack them - momentum is king :-)
