Theoretically you can go crazy and punch down however you like as long as it’s the same on both ends. Same goes for store-bought patch cables. Technically some pairs are more tightly twisted so you will see better performance/less interference using one of the standards, but I doubt anyone would see a real-world difference on modern equipment.
If you want to be a standards-compliant dweeb, use B.
I discovered how much making patch cables sucks, and if I had to do that for a living, I’d quit my job and go tend bar at a smokey jazz club somewhere. I may do that anyway. But if you only need say 8 or 10, I’d bite the bullet and make my own to the desired length. Excessive and unkempt cable lengths drive me nuts. I would not, however, make hundreds. Or even dozens.
Crimping is the easy part. It’s punching down those damn tiny wires. There is something satisfying about custom lengths though.
And to echo Waldo’s comment about A vs B…copper wire is copper wire, irrespective of the color of sheathing. As long as it’s the same configuration on both ends of a connection, it’s simply a pass thru of the signal. So you can use A cables on a B jack, as long as both ends of the cable are A.
I have this app called “Parcel” that tracks your packages and syncs automatically with Amazon. It’s great…until you order a shit-ton of stuff for your home network and Amazon divides it all up into the smallest groups possible so that you have eleventy deliveries coming today.
The tracking updates have my phone buzzing more than your Mom’s vibrator.
Amazon is famous for “we can make these nine deliveries to your house tomorrow. Or we can bundle them in the smallest number of packages and trips to your house and have it to you in September. Your choice. Same price.”
Time Machine back-ups. I have an aging Buffalo Linkstation for this but, as I’m installing a rack, it seems like an opportune time to update this. I can buy two Mac minis for the price of some of these rack-mounted enclosures!
