Hi,
I have no clue what Glamour and FX mean - or how to tell if the seat is 1st, 2nd or whatever generation - but I use the SSM aspide on all my bikes and love it. Mine is the naked carbon version, the older model used to say 'composite' on the side, the newest one says 'superleggera' but they are the same saddle. The decals and colors have changed a bit over the last few years.
It is the lightest and most comfortable saddle I ever owned, I would highly recommend it if the size fits you. I think it's like 120-something mm wide and 280 long or something like that. Awesome seat!
Hope this helps
