Well for the scale, everything is the same.  They didn't change it, just added on.  Numbers still mean the same thing, just that the max is higher since the goliath came out.

Now, truthfully, neither of the two you listed will work well.  The intense will be better for lighter conditions, but will NOT help your over/under at all, probalby make it worse.  The absolute coudl help with that, but it isn't for light oil so it'd burn up.  Maybe a strongly drilled slayr will work, and perhaps change the surface.

There are alot of things that can cause over under. since i dont know you specs and style i can only give out more general approach. usaully a snappy drilling might cause the ball to go to long and not read the lane enough then over compensating take into effect. another thing is that when a backend ball is drilled for length it can came out of the oil into the backend with a sharp angle and when taken off make push through the oil too much. anything thing you need else covered ask me but what i would do depending how dry the lane is is to get a weaker ball but drill it to have a smooother reaction so it wont be as unpredictable when it comes out of the pattern or starts hooking.
