Reddit mentions of ABUS 64TI/50 C KD Titalium Aluminum Alloy Keyd Different Padlock 2-Inch with 5/16-Inch Diameter Nano Protect Steel Shackle

For the Abus 64TI/50, I use the Peterson .040 pry bar and Peterson hook 1 in .018. Once you've picked it a few times and know the binding order, the lock becomes pretty easy to pick consistently.

The Master Lock 570 is a challenging lock due to the dead core. I recommend working your way up to this lock. The Master Lock 140, Brinks 40mm (non-brass), and Abus 55/40. For these locks I use Sparrows' BOK tension and Peterson hook 1 in .025.

Once you've got these down, you can step up to the Paclock 90A, Master Lock 410, and American 1100. For these locks I'll use the previously mentioned Peterson hook 1 in .018, Peterson hook 7 in .018, the previously mentioned Peterson .040 pry bar, and the Peterson .050 pry bar.

Good luck!

I've flown with a good size padlock several times.

Also usually bring a couple good quality carabiners (I like the locking ones).

that doesn't seem right.

64TI/30 1.25 body 3/16 shackle 4 pins

only thing different is second number. The second number seems to deal with both the body and the shackle. And even though the first number is the same for all 3, the first two has 5 pins and the last one has 4 pins. Nothing on the types of pin in description
