ahhhhhh I feel your pain.
First I was told string the crosses 2-3lbs less for the reason you mentioned, and this is what most pros currently do for full poly.
Now I hear we should string them the same or slightly tighter in the cross.
I think more then anything its personal.
Try 54/52 , then try
then try 53 53, or even try 48/56 why not right?
then by then there will be some new holy grail of tension to follow
