Certainly moving out of box 1 of the pents can help. I found it helpful to extend what I was comfortable with. On the B and E strings, find the pent notes up a couple of frets and on the E and A strings, find the pent notes down a couple of frets. In the middle, find how you can slide up to the next shape, or down. Once you learn how to connect the shapes up and down the neck you can really unlock your playing.

However, something that really struck me when I started here was that Anders would play in position using a single pent shape in his blues lessons here. He would play some really awesome stuff...staying in that one position. It demonstrated to me that I needed to learn to use what I knew already better...not more shapes or scales.
