Without much thought I'm thinking 98, 87 or 97. The central location makes it so there are a lot of hands that you dominate and that dominate you. Hence the information is quite valuable. It shouldn't be something like AK or 34 because the chance of the information being useful (ie you actually make a different decision based on the information than you would have in the dark) is going to be less with those hands. With these middle of the deck hands it should be higher.
