the whole teak vs. non-teak is one of personal preference, and maint.issues.
I love teak, but I also do my own maint. I'm an oiler. No Cetol, Epiphanes, varnish, 14 coats, plus yearly sanding, and touch-up for me. A rag, a quart of oil and a kid just work out better for me.
I've seen more than my share of teak that hasn't been maintained and it looks like hell. Add in that on a deck, you've most likely got a gazillion holes screwing it down, leaves me conflicted. But I love the look of a teak deck. go figure.
