Kinesis XC130
Cotic Soul
???????????
Currently being swayed more towards the Soul but the Kinesis has tickled my fancy.
Alternatively I've seen 2012 and 2013 Whyte 905's going from between £1000-1200 brand new, which is roughly the same price as a self-build would cost with Reba forks and sLX / XT kit.
Carbon 456?
I run mine somewhere between 120mm and 130mm, it's fairly lightweight and I think it's quite robust
456 better suited to 130 -140 I reckon
I'd be really tempted by the current offer on the Soul if I were you.
Having had and really enjoyed a Blizzard in 2006, I had to get another 853 tubed HT. I was extremely impressed with Cotic from a sales and service perspective and the Soul's frame more than made up for 6 years without my Blizzard as a winter bike.
I'd say Soul.. not simply because 853 steel is (imo) better suited than 4130, alloy or carbon for a fun HT, but because I'm impressed with the quality of the Soul and their desire to sell you the right frame.. its also 31.6mm dropper post compatible.
My Soul with Fox 32 talas 120/140, 1x10, XT, DOSS, DT EX1750's and 2.4RQ's is 27lbs.. and its fun
However, once Pace get the RC127 out there.. I'm headed that way...

Can't speak for the Kinesis... Definitely not the Bred, they're orrible with a longer fork, just ride like you'd expect any 100mm xc frame with too much fork in to ride. I switched from my Scandal to a Soul and it was like the difference between a dog shit sandwich and a steak cooked by God.
