I pick my front door lock by a Short Hook in 1 min, Jag Snake in about 10 sec, and Pick Gun in only 1 sec (faster than using key

But I can't pick it by using Diamond, Snake Rake and any others.
I know Diamond and Snake Rake are the two most recommend by those professional. But I just can't successfully manipulate them.
Also, I can't feel the force that come from the spring by not using Hook. I don't know how to rake, so I must feel that force.
