This is when trad only climbers could use a bit of sport in their life. MT is not a sandbag, most trad climbers are just not used to getting that steep. body position for rests on steep routes is key. Can get a good shake out here. I find the move up onto the sloper ledge after is harder than the actual roof.

Here's Rumney 5.9 bottom section is as short and steep as the MT roof.

looks a lot like this. minus the bomber knee bar you get on MT
