Rode the Ksyriums yesterday. Seemed slow. Seemed industrially strong none of the light sprinty feel of my old DA's. Wife is travelling for the week so I may give her DA C24's a shot. Then I'll probably order the King and Open Pro setup as I am just thinking the carbon/aluminum bond of the C24 is kinda scary for 45 mph plus descents with my 200 lb bulk on 'em... Wishing there was a good, light weight UST rim option ...
I wouldn't worry about Shimano stuff failing really, they may lack excitement but their stuff is very well engineered. From people who have ridden road tubeless I have heard it isn't really worth the hassle.
