Took Gordon Airporte's suggestion and bought a Brinks 101-42001 today. This one has two spool pins.
Whew It took me and hour to pick it three times. Definitely more difficult than any other locks in my collection.
As I said. I did pick it successfully multiple times, but I'm not exactly sure what needs to happen in order for everything to come together. I can't pick it reliably yet. Will have to spend some real time with this lock to get the feeling for the spools.
Definitely a step up for me. A nice little 5 dollar investment.
Thx for the suggestion Gordon.
