Nothing lasts forever.

Treated wood decking is about 1/3 the cost of the synthetic stuff.
It will probably last a good 20 years.

I have just finished installing 5000 square feet of Trex decking. You have to allow for expansion and contraction with it. It looks great now, but I honestly don't know how long that will last.

That said, if you really love the Tiger Wood, then go for it.
16 x 16 isn't so huge that it makes much difference.

Congrats on your new home!
