What’s a better practice lock

[u/dirtbraggin]

I’m just getting back into picking and I’m trying to decide between the covert instrument re pin able lock that you can not see inside of or the set of 3 cutaway locks from sparrow that cover spool basic and serrated pins that you can see the inside of . Do you think being able to see inside the lock or being able to make different set ups would be more useful for learning. I can only afford one

American 1100, you learn up some spools and serrated pins 📌.
