Lightweight carbon XC or carbon Cyclocross?

[Hugo Stiglitz]

Basically Im 99% on a drop bar carbon cyclocross but I have fond memories of a scandium XC mtb.

Watching Leadville 100 and most of my riding on the bike would be similar to XC (60:40 pavement:rough). I could even cross over to my usual mtb rides on singletrack.

Any similar dilemmas? What did you do?

I dont have room for one of each!

I have an ex-cyclocross bike with wide ratio gears that I love for longer rides like the Dartmoor way, lanes etc.
I have an MTB with decent front forks.

As I'm not racing, or even trying hard to keep up with mates, I could do the Dartmoor Way very happily on the MTB with suitable tyres.
So what if I cover a few less miles? Or take an extra day?
I'd not want to try using the drop bar bike around the woods where the MTB comes into its own, so if I had to have just one bike, it would be some kind of MTB.
It would be different if I had reason to focus on particular rides, or if I was trying to be competitive.
People have to work out their own priorities.

The other thing is, as with boats, it can be good to focus on one aspect for a year or three, then shift to a different flavour.
That may mean selling last year's toy, or leaving it in a shed somewhere.
