What is Reddit's opinion of ABUS 64TI/50 C Titalium Aluminum Alloy Padlock Keyed Different?

From 3.5 billion Reddit comments

Hell yeah, it's all about sharing the info and helping out. It's not a competition, it's a co-op. :)

Everything on that list is less than 10 bucks. Those 64ti you can get on amazon for 6 bucks (https://smile.amazon.com/gp/product/B00G7P3BQM go to the bottom or on the right side and you'll see them from another seller for 5.88 each with prime shipping)

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. https://www.amazon.com/ABUS-64TI-50-KD-Titalium/dp/B00G7P3BQM/ref=pd_sim_60_3?_encoding=UTF8&psc=1&refRID=F3YQATJK4528FBQBQE30 64ti/50 - 2 inch body 5/16 shackle 5 pin

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
