Look I like FT I really do but in a small collection due to it's layout I think it would get old much sooner than RZ would. FT is a bit overrated due to it's limited lastability IMO. I think RZ would hold up much better in a small collection. I was surprised by how much I liked RZ and even more surprised that many of my friends & family love playing it as well. That said, if there is any way for you to get some play time on RZ first that would probably be the best way to go as we all have our unique taste.
As far as build quality, I've had plenty of NIB pins. RZ my newest pin is every bit as solid and probably better quality than most of them if not all. I totally disagree with everything in the post above mine
