I had some Trex decking installed last year. Funnily enough Island Mist colour. I was going to install it, but we just had the garden done, and her indoors could wait for me to do it
I was going to install composite frame work as well, but could not afford that with someone installing it. Used the Trex Protect tape as a compromise.
The pros are low maintenance, no friggin painting etc. Cons are it can get a bit too hot for bear feet in full sun, and expands a bit, so tends to knock the joints out.
Ultimately I would have it again.
