I picked my first "High Security" lock within a week of picking my first lock ever. (5 pin tumbler, 4 Spool pins, popped it within 4 minutes first try.)
You've got a lot more experience than I did at that point so you're definitely ready!
Just remember, FEATHER light tension is the way to go. Picking HARDER is not picking BETTER.
Btw, give my love to Dagney next time you see her and tell John I said Howdy.
