Have you considered Bontrager tyres?
I had dismissed them as the tread patterns were very 1990's but they've been updated and look rather nice.
I have XR2 Team Issue (rear) and XR3 Team Issue (front) for my all round, ride anywhere wheelset. I think a pair of XR2's or XR1 (rear), XR2 (front) could be great for racing.
+ Grippiest rubber compound of the big players (found Schwalbe and Maxxis rubber to be a bit hard and plasticy and lacked traction on slick rocks and roots that litter courses even when the ground is otherwise dry)
+ Very robust sidewalls (happily ride all day in the rocks of the Welsh mountains without worry)
+ Robust rubber around the tread (most XC tyres still have thin rubber around the tread even in reinforced versions which reinforce the sidewall only- no help at all when you get cuts and thorns going in around the tread area!)
+ Fast rolling (XR2 especially)
+ Go up tubeless first time, even with a hand pump, without putting a tube in first!
+ Super easy to seal tubeless (hold air perfectly fine without sealant)
+ 2.2 is the smallest size for most tyres so gives a pretty reasonable air volume
- Potentially a touch expensive
- That grippy compound will wear quicker than more "plastic" tyres
- They aren't the lightest. XR2 2.2 Team Issue (26 inch) were 564g average (580g claimed). I consider this the upper limit of acceptable for a race tyre but the trade off is awesome grip, tacky compound, super robust fit and forget tyres.
Some stuff to consider maybe?
