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...
