I'm not sure about the difficulty of that lock so hopefully someone else will chime in if that's a good lock to start with spools on. But as for picking spools; When you pick it to a false set, that is when the plug turns a bit but doesn't open, the grove of the spool pin is stuck between the plug and the shell.
To find the spool pin you push up on each of them until you find one causes the plug to counter rotate. You'll feel it pushing back in your tension wrench if you're not using too much. Once you find the spool pin carefully push up on it while lightening the tension until the point where you get it to move out of the little pocket of the spool and above the sheer line. It's easy to overset the bottom pin while doing this so be careful. If the lock doesn't open look for other spool pins with the same method, or it could be that you overset a pin or that some others have fallen when the plug rotated back slightly.
Light tension is key for spool pins.
Search the site for more info on spools, there's a lot of good knowledge here. Remember, don't pick locks you don't own or that are in use.
Welcome to site and happy picking
