Most tree's are .370, as far as how much delay on a full tree, it depends on how well your car reacts. If you can cut a light on a pro tree and carry some delay to do it, I would start at around 1.150. When I did bracket race, I would usually be in the 1.160-1.170 range. That being said, I usually carry 30 to 40 numbers on a pro tree.
