Do the slimline lockpicks (such as Southord's C1510) also work well on American locks and locks with larger keyways. I'm looking for a good starter set and even though I live in the United States (and plan to work mostly with US locks) I want a versatile starter set. If they do, is there any advantage to getting an equivalent non-slimline MPXS-14 set from Southord?
Also is there any practical advantage to starting out with a more expensive set from Peterson? I also tried looking for HPC, Rytan and Falle-Safe but couldn't find them for sale (online). Is there any advantage to starting out with any of these rather than Southords?
Thanks in advance.
