I'm having a hard time thinking about parting with this frame just for the sake of something lighter (though this is weightweenies and I am one). It fits perfectly, is super stiff & responsive, looks great, and a Swiss edition that is no longer made. I'm just getting a little bored with the build but can't decide what to do.

So here's what I'd like to hear your thoughts on these options. I'm no longer racing, maybe 1 or 2 a season, so I don't worry too much about going down and killing nice parts. It's more about doing group rides, centuries, and solos.
XXX-lites gone, replaced with 900g Reynolds MV32T's
Thoughts on these options.
1. Replace frame with Foil, addict sl, Moots RSL, Cervelo R5...old parts.
OR
2. (keep frame) Replace groupo with Red22 or Record 11, EE brakes, New Ultimate bar,stem and Aican cables/housing.
OR
3. (keep frame/groupo) New wheelset, Enve 45, 3.4 clinchers or new Reynolds Assault clincher with tune 70/170.
Thanks in advance
