The trail at the leaning tree is called cardiac bypass, since it gets you to the top where the cardiac trail also goes. Rollie starts at at the top where the cardiac and cardiac bypass meet.
Candyass is on the 517 side of the mountain. The trails near the fence will eventually end up at the boy scout camp. The one named trail in there is called "the middle". It pretty much runs along the west border of the boy scouts camp.
Take a look at the jorba map and the pile of spaghetti zig zagging on the west side of the mountain is candyass. Rollie is the south arc of the small loop near the peak of the mountain. If Rollie messed you up, candyass will definitely make you feel worse. The first two times I rode that trail I got a flat.
