Which disc-brake CX suits my needs?

Hello everyone!

I'm new to this forum and new to the whole cyclocross community. Here's the story.

I want to buy my first cx bike but I'm hesitating which one I should choose. I have narrowed my choices to Felt F65X 2014 and Boardman CX Pro. After shipping cost and all duties the prices are: 1900$ for Felt and 2100$ for Boardman. I want to buy an all-rounder for both cyclocross and leisure rides.

For winter season, I intend to use the bike with cycletrainer - Tacx Satori. Do anyone happen to know if these bikes are compatible with the cycletrainer? I've heard that carbon bikes may be damaged by cycletrainers [e.g. Cube's FAQ section] and, as far as I know, Boardman's fork is fully carbon while Felt's is partially carbon. However, the frame is aluminium in both cases.

I would be tremendously grateful if you could tell me which bike's better for me [please, list the reasons why it's better]. Recommending the right size for me will be much appreciated. My measurements are as follows: height – 165,5 cm, leg length (inseam) – 75,5 cm [for clarification: I'm an adult so I'm quite short]. I guess 50 cm should be right.

If you find other bikes to be superior to the ones I listed, feel free to insert them in your reply. I'm especially interested in any bargains for both the bikes I listed and any other worthy attention. So, if you know a shop which sells Felt or Boardman for less than I found, let me know.

I give you many thanks in advance for your helping hand.

Regards,

P.S. Sorry for the long post, hope you forgive me.
