Any of you heard of these sayings?
For you ladies out there: There are many little black dresses out there but there's only one that make me feel sexy.
For you man out there: This is my rifle, there's many out out there but there's no one like mine...or something like that

That's how you should approach shopping for LR's or base rocks....they all look so different but yet the same...you should get the ones that make your tank look just right
You might end up paying more...but it will be so worth it in the end when you tank turns out just right
Just don't make a common mistake by buying in bulk sight unseen...you might just end up with 500lbs of LR's all the same size...it's almost impossible to aquascape to your satisfaction and still have decent flow with no natural looks, caves and canvern to house your fish
Put it this way...my most favorite piece of LR is about 75lbs with 8 different "shelves" :cheer:
Keep in mind every piece of corals you add will also come on a piece of rock...if you decorated your tank with LR's already to your liking before you add corals...it might look too full later...
sorry...so long
