Tomorrow is the fall bike blowout here in Toronto and I've been itchin' to spend some money. I have three options and cannot decide which to go with.

Option 1
I have 2010 Felt AR4 frameset and a full DA7900 groupset. All I would need to buy is a stem, handlebars, bar wrap, and a chain to get it going. This is the cheapest option, although I'm not entirely enamored with the frame and find the aero ride kind of harsh. I could sell it and the groupset for somewhere in the neighborhood of $1,500 - $1,700

Option 2
Buy a 2013 BMC GF01 Ultegra Di2 for $4,200. I tested the bike yesterday and really liked it. I would sell the wheelset and crank for whatever I can get.



Option 3
Buy a 2013 Tarmac s works SL4 frameset for $1,799 and use the DA7900 group I already have or buy a new Ultegra Di2 group. I would also have to buy a stem, handlebars, bar wrap, and a chain.



I realize the Tarmac and GF01 are very different geometry and I'm not sure if either of these would replace my primary bike (which I love) or just be another bike. The tarmac is much closer to what I'm currently riding. Which option would you choose?
