Roger,
I have an Assault pearl on the way specs are 3.5 top and 4 inch pin.  What do you think of putting a 5x3 drilling on it.  Any thoughts or recommendations

Here my current

SS particle   3 3/8 stacked

SS Solid 4x5

SS pearl 5.5x5

Sonic x 5X4

Top Fuel 4X4

Great choice for layout.  Sorry about the delayed response I just hate giving answers out left and right with out thinking about them clearly.  It is going to handle similar conditions that your Silver Streak Pearl handles, but with more midlane and control.  That is why I like your layout choice going stronger kicking the MB right on top of having the 2% pearl particle coverstock giving you a nice controlled reaction with a pearl look.  Will be less skid flippy as your silver streak pearl and handle carry down better.  

Thanks,
