Steve.. as Jim stated, it is definetly a question of personal preference when given the means to build your own table.
One of the things I wish I had done with my table was to have given myself an extra couple of inches of overhang all the way around for clamping purposes. When not using my table for routing, I make use of it as an additional workbench. While I don't "hammer" on it, I do use it for clamping down objects by making use of some "T" tracks i installed on the back half. (my LS positioner is removable) The T tracks work fine for most intended applications, mostly pocket hole screw assemblies, however, ya can't beat a good "F" style clamp.
just my 2 cents.. but something to consider..
