Sounds like you had...errrmmm...fun.
I find onsighting pretty hard at Cheedale due to the routes being quite tricky to "read" in most cases. However, this IS sport climbing, and the routes being tricky to onsight isn't necessarily reason to abandon Max Wall altogether.
I thought Max Head Room, the 7a immediately right and Max to the Wall would be onsightable...although that's not to say I onsighted them.
I don't think Quality Control differs too much in style from the other routes of similar grade down there, apart from it being very low in the grade.
