In my opinion some of the best traction out there is the Xtrak stuff that the wakeoutlaws guys sell. The "Longbow". It is lightweight and covers pretty much the whole board. Only problem is it will cover up your new graphic.
You can go with Hula Dek (available from Surfsource) -- it is a clear liquid that has clear sandpaper like granules that you roll on. I've got it on a few boards and it works great. You can see right through it. Super cheap at about $15 for a bottle.
Another one is a clear grip tape that is available from NorthShore Inc. Probably cost you around $40.
