Are you seriously throwing a hissy fit because you didn't get the answer you were expecting? You asked what the ideal pick for a dexter lock was, it doesn't work like that.
There is no "ideal pick" for any particular lock. You start off with a short or medium hook, and if the lock isn't playing ball, you should be able to tell what the problem is and choose a pick you feel will do the job easier. You're not experienced enough to be able to figure that out yet, nothing wrong with that... and of course we're here to help, but it seems to me that you're concentrating on the wrong stuff. It's not a case of finding the right pick, you can pick almost anything with a basic short hook.
So far you've picked a cheap chinese padlock and a cabinet lock, which I'll assume was a wafer type. Those are both cheap and nasty locks, which can be opened with very basic understanding and it doesn't take much skill... I'll put it this way, if you went with random picks and wiggled them around until you found one that worked, it wouldn't have taken long to crack those. But now you're at the door lock, changing picks every 30 seconds or so, and can't seem to find the "right pick" for it.
Don't take offense and throw another wobbly, that's exactly what I did when I first started... do yourself a favour, take the time to learn the theory properly and pay attention to the pins.
If you don't fully understand how the mechanism works along with tolerances and binding order, do your homework before attempting to pick anything half decent. And don't say you know all this already cos if you did, you wouldn't be asking what the best pick for your exact lock was.
Like all trades time, effort and common sense are the key. I guess i got over exited by those cheap ass pick i did on a very inexpensive locks, however that same day I was able to open two of my gun locks, one a master 107 the other 10000ptr-4,
