Amount of Live Rock Question

With the research that I did before purchasing my first tank about 7 weeks ago, most everything I read said I should add a minimum of 1 pound of live rock for every gallon in my tank, but that 1.5 - 2 pounds would be better.  I purchased a 29 G tank and initially added 30 pounds of cured live rock and a couple of weeks later added 5 more pounds of cured live rock.  I have been purchasing some softies and some of them are attached to some sizeable pieces of live rock, so I'd guess I now have about 40 pounds of Live Rock.  It seems that there is a "movement" among some reef keepers to have a more limited amount of rock in their tanks (you even have a term to describe this style that I've seen on the boards, but I can't think of it right now).  I am feeling as though my tank is overfilled with live rock and that my fish don't have much open space to swim around.  Is there another thought process out there now that we don't need as much live rock as people originally thought we did?  I'm not sure I want all of the rock I have in my tank, but perhaps I should keep it there and when I upgrade to a much larger tank around year end I can move it to that tank. 

The amount of space rock takes up in your tank should be one consideration. Since rock displaces water that means less water your fish have to live in. Also, dense, less poreous rock is heavier. Light weight, poreous rock is better. You want to provide a home for bacteria and other micro/macro fauna. Simple answer is to do what looks good to you!

Another factor to consider is having enough places for your livestock to hide when feeling threatened (or bed time). I started my 72 bow with only 50 lbs of rock and liked all the open space, but quickly noticed that i didnt have enough caves and nooks for all the fish to hide in.
