Firing pin strength , to much?

I'm getting ready to recieve my bolt back from Robar after having them NP-3 coat it and was wondering about what weight firing pin spring to use , I have seen up to 30lbs but the factory is like 17lbs I think , I'm using a custom ultralite pin from Gregg Tannel thats has a steel head and shoulder with an aluminum body , all the internals of the bolt were also coated so their is gonna be minimal friction and binding.

The question is should I use a standard spring that Holland offers at about 19lbs or get a heavier spring to yet further decrease lock time

I wouldnt go much more than a 23# spring, it dont happen very often but a strong spring can cause accuracy issues.
