Facchinetti padlock with inox springs

[Mememe]

I'm having trouble pin picking a Facchinetti padlock (L80 70 00): 5 pins (2 security) + inox springs.

You can find the lock on http://www.facchinetti.it/padlocks.htm

The challenge I am having is getting the tension right. I've tried everything from light to heavy and I still can't pop it. Raking works every now and again but I want to pick it.

Any special advice on inox spings or on this particular lock?

Thanks

Solved:

The problem wasn't the lock. The problem was the pick I selected. I tend to favour a small half-diamond which was too small for this lock. By changing to a larger half-diamond I can single pick the the lock in seconds. As for raking, a single stroke of a Jag pick does the business.
