Unless I am very much mistaken, the XHD springs are not the same as SS springs, which is what you are describing. The later are really drag only springs, while XHD is just higher rate and should be the same number of leaves right to left.
If you are compensating for unevenness of your leafs by adjusting your TBs, and you are running this on the street - well - that does not sound like a good plan to me ... but it's your nickel.
