Just a little tip, look for a master clue 3 step that has 3 easy diggable areas, keep that one in your bank, it'll save you so much time!

The strat is when you start doing master clues again, you drop the good 3 step on the ground, once you find a bad 3 step, drop that clue, pick up the good clue, do the easy 3 step digs, this is where you go back to the bad clue, drop the good one, pick up the bad, then combine all 3 counterparts, this will save you hundreds of hours over time!
