There are many things you need to consider before buying artificial.  To name a few you need to find a good artificial turf company you want to work with and you think are worthy of your business.  Next, what Kind of turf you want in your yard.  Do you want tall, short, light green, dark green, with brown thatch, green thatch or no thatch at all.  Do you want nylon or Polypropylene?  Do you want multi color configurations or one color grass.  Do you want soft turf or do you want stiff blade high traffic area turf?  Do you want to keep your sprinklers in for cooling and rinsing the turf.  Now you can see there a lot of things you need to considering when buying artificial turf.  

Here is what I did.  I gave a 5 star rating to Global Syn Turf for being the actual artificial turf manufacturer and giving me a real manufacturer's warranty for 15 years.  They sent me a lot of artificial turf samples for free and the representative on the phone walked me through all their different turf choices.  I ended up purchasing the SuperNatural 80 through their artificial turf dealer in Los Angles.  Thanks again...

Is there a reason for the different blade shapes? What makes them different from each other? Which one is best for residential purposes? What about for pets?
