Frameset - Supersix evo hm 2015 vs canyon aeroad vs Cervelo R3-SL vs s-works tarmac 2015

[shing1919]

HEY GUYS,

I wanna upgrade the frameset. (mine is cervelo r3-sL.)
I checked the Cannondle supersix evo hi-mod di2 2015, s-works tarmac 2015 and canyon aeroad.
I found that the old evo hi-mod's price is very attractive!
but I check from the roadbike.de, tarmac's bottom bracket stiffness is quite high.
Is bottom brakcet stiffness an important factor to choose a bike frame? (should I compare with the comfort and weight too?)
or should I choose an aero bike I only tried my friend's s2, but it so too soft
Can any owner of those bikes share your experince?
Can anyone give me some suggestions lol

I am pre-disposed to Cannondale, but know people with all the frames you mention and all are very happy, so pick the one that appeals to (and fits) you the most and I'm sure you'll be happy too.

cheers
