We must make the assumption that you have researched the Best type cores with two shear lines so you know how the core is constructed. You mentioned having definite 'sets' on the pins. Unfortunately each set could have been for either shear line. There is no way to know for sure until the lock opens. Since the core removal lug only rotates to the right (CW) try picking to the left. If the plug turns and is picked but stll does not open the padlock, spin it to the right with a plug spinner.
Yes, Best locks do occasionally have spool security pins. They have been used on bottom pins as well as the control and top pins. With two shear lines, the spool can be sticking on either.
With medium turning pressure, try moving one pin to the set. If the depth appears to be a deep key cut, gently lighten the pressure and move the same pin to a higher set. You might get lucky and ferret out the correct opening sets.
Nothing is foolproof to a talented fool. Wisdom is not just in determining how to do something, but also includes determining whether it should be done at all.
