OP, that's a killer socket set. I'm jealous.
I have a bit of love/hate with the hansen trays.
I really like the pegs with the sizes written on them. Makes it super fast to grab sockets in a hurry.
On the other hand, they're not the best use of space. They do take up valuable square inches. But I've yet to find anything that works better. Yeah, there are lots of peg based socket trays, but nothing else seems to have the easily seen size markings like the Hansen trays.
I don't have a complete set yet. I am slowly building a full set of sockets. I have a mix of brands, and I buy Snap-On when I can.
I still need 1/4" 12 point, 3/8" impact, 12pt metric 1/2" chrome, and 6 point SAE 1/2" chrome.
