'In' is for thicker or more delicate string.
Sometimes flicking the gripper a couple of times before inserting the string can free it up so that it doesn't lock up on the string.
And yes, there is an adjustment screw on the tension head. If the string is slipping, you can tighten it. If the string is being smashed, you can loosen it. When I used my crank head, I adjusted it so it didn't ghost natural gut.
