First came seatpost. in 1997. Stem came year latter.
Wether to use it, depends on the build and how fundamentalist you want to get

I wouldnt probably do it. If you wnt to go RF, then in 95 they had very different cromoly stem.. that one would suit better i guess.
But SYstem is definatelly very nice. Seatpost is ok in zero offset version. The bigger offset one i cannot stand. seatpost clamping head is too distracting IMO. also quite heavy.
