hi i am pretty new myself at picking about 2 weeks. i have just seen the suggestion a couple of times to but a lock and remove a few pins. i hve recently tried this i bought a cheap 11 dollar kwickset deadbolt. unfortunately even though i had read it happening all the time and knew how to prevent it i bound the springs in and messed up two of them so at max i can only add three pins now it is still extreamly helpful. i started with one then added until 3 then switched those around.
anyways after i was done i picked up a lock i had been having trouble with and i could feel the pins a ton better. if you are even semi serious about the hobby it is definately worth the money i was not very thourough in explaining how to do it but the elder members in the group have done a great job at this in other topic lists
