I'm wondering if there's anyone with composite decking who might share their thoughts on whether they are happy with it, and how it wears.  
 
I have my deck framed, and had the decking delivered yesterday. The problem is that about 2/3 of the boards show some scuff marks. The supplier is willing to work with me to replace the boards in question, or give me a discount.  
 
My question is, is the decking just going to scuff up anyway? Maybe the replacement boards could be scuffed too. Then I've lost 2 weeks, and winter could be upon us. I love the idea of zero maintenance, but if it starts looking all scuffed and worn right away, is it worth the extra cost? Cost, by the way, is about triple what pressure treated lumber would be.  
 
Thanks for your thoughts.
