Ben Pearson 956 brace height query

[Longbow1415]

Hi
I've just purchased a Ben Pearson 956 takedown. It's 66", and 52@28. I'm not familiar with this type of bow. Need to make a string, as it doesn't have one. Can anyone, with experience, point in the direction of the correct brace height for this bow?
Any advice is much appreciated, thank you!

7" is a good starting point
