What's Your Achilles Heel?

For me, if it has more than 5 pin stacks it takes twice as long or longer for me to manipulate.

You can load a 5 stack with security pins, whatever and I am confident it'll be open within 5 minutes. 7 if I am having a bad day.
The minute it has 6 or 7 sets, I lose my ability and feel reduced to luck more than skill. And then it takes 15 minutes.

What confounds you?

I still can't get a Bilock picked, I get plug rotation 4-5 times through spp or raking at which point it falls into a deep false set. At this point I can set the interactive element but nothing else after. Makes me want to find one that's heavily mastered to increase my chances. Also many of the radially pinned locks give me trouble. There is about 4 of those sitting on my desk unpicked.

I'm lucky in that my everyday experience is a school system mostly built in the 1950s and 1960s. And there are a bazillion schools in the district.

Old Schlage or Kwitsets are about the toughest challenge. Unless you run into a "special" case like a biology lab and someone decided to load it up with serrated or spool pins.

brass body padlocks like WB, Herculock and CCL. I can rake them, but really struggle with SPP. can't think of a good reason why. always been frustrating and a motivation killer.

The Abus Titalium. I think something about the alloy makes feedback almost disappear.

I have off-days when I cannot seem to pick anything. I've conquered a several ABUS and a couple Best SFICs and on some days this one 40mm aluminum Master kicks my butt. On the other hand, when I have good picking days I really impress myself. I have yet to get into higher end locks like Medeco. I have a few Euro cylinders that I cannot pick for the life of me.

Mine is padlocks with strong spring tension. I usially end up raking padlocks if the spring is too tough. I am sure a lot of it is just my own inexperience

[AngryHatter]

I think I've solved mine.
Mental block.
If five stacks are no sweat, set the five and determine which is not set.

Man, I can be dense as lead.
