Bike No.2 - Help please

Slow1

Hi

Am looking to step up to Carbon, but need a few pointers. So please help!

I am a big lad 6'2' and 100kg (but falling).

I ride mainly for fitness and do 60-90 min sessions during the week and a longer 3 to 4 hour ride at weekend. I may have a go at a sprint triathlon next year but don't think i should include this in my bike selection thinking at this stage,

I have a half decent ali bike with 105 bits at present but am looking for something a bit more comfortable and stiffer. Can someone clarify if:
(i) I will genuinely get much benefit from a carbon frame,
(ii) whether the Sportive vs Race bike thing is really a material issue and hw i should think about it practically
(iii) is weight/size a consideration?
(iv) are wheels more important than components?

I would also like to feel more confident going down hills at speed.

Potential Shopping list includes (focused on Ultegra):
Spec Roubaix SL3 Expert
Cannondale Super6 Ultegra
Bianchi Sempre or Infinito Ultegra
Felt..maybe
Scott CR1 or Foil

Cheers :?:

The Cannondale Supersix is meant to be super stiff, or so I've heard, so for long rides it probably wouldn't be as comfortable as the Roubaix or Infinito which are aimed more at a day in the saddle.

As for wheels or components, wheels, but i'd imagine they all come with a fairly decent wheelset anyway.

Any views on Bianchi reliability/warranty stuff?

Cheers again!

I've no experience of Bianchi warranty, not needed to as my Bianchi Via Nirone has been very very reliable, never had a problem with it and it gets used at least 3 days a week on my commute, I've been very happy with it as i'd imagine you would an Infinito or Sempre.
