As the subject suggests…as its winter I’m using my winter bike obviously, should I just use my good bike (well good for me – carbon frame, full Ultegra) on the turbo?

Are the stories about turbos being bad for frames just that – stories?

Only other thing is the wheel I use on the turbo is an old one with a 9 speed cassette with a turbo tyre on it, that should work okay with 11 speed shouldnt it? Or does that risk killing the cassette and chain?

You should be OK so long as you do not stand up. Most carbon bikes are not made to take the extra torsion across the dropouts – so most of the manufacturers do not extend their warranty for this use case.

I have been using my (all carbon) Battaglin C12 happily enough – but I *never* honk out of the saddle. 

Arguably if you want a stood up session then use the gym and book a spin class.

Mine flexes a fair bit but it’s all good.

Can’t see any issue with your choice of wheel – only issue will be gear changes I guess.  I picked up a cheap rear and chucked my old 11 spd cassette on there with a turbo.  Works a treat!

Mine flexes a lot under my very low power pedalling.

As my Trek frame has a lifetime guarantee I’m not too worried.

Well my Boardman has been on
Well my Boardman has been on my turbo since September last year. I’ll let you know in March if it has suffered. It’s quite surprising how much a frame flexes under high power pedaling.
