The cut will be determined by the number of players participating and the leading score after 2 rounds so I can not give you a fix number just yet.
If you read the info carefully you'll see that round 2 is a ranked round and therefore the Pros would be hitting off their normal tees not the master tees. In choosing the course conditions and other important issues I always keep it in mind to create a decent playing field for the pros to compete against the masters. Its very difficult to hold tournaments for both tiers together so this is the best I can do under the circumstances.
