Gotta get to n-1 or n-2. So hard!

OK, here's my stable:

2014 Ciocc San Cristobal w/7700 (downtube shifters)
2006 Bianchi Pinella w/Ultegra 10
2005 Bianchi Luna w/Ultegra 10
2001 Gunnar Rockhound w/LX/XTR
1998 Gunnar Crosshairs with 7700/XTR

Framesets:
2017 Lynskey R265
20xx Ritchey Titanium Breakaway
1996 Bianchi ELOS

I've got too many bikes but I can't decide what to get rid of.
I've thought of keeping one each of carbon, steel and titanium and the MTB.
But I don't really like the carbon bike that much.
