Just starting to research this type of bike aswell and come up with this.

Saddle is down to getting the right one in the first place and then setting it up for your butt. Similarly with the Bars.

Whyte are mainly noted for their top end Mountain bikes and the are good and this is their first foray into CX. So new in fact that I haven't found a shop with one to even look at- let alone test ride. However the few reports in magazines have been very favourable so I will keep looking for one.
