Which resistance jazz pup for bridge?

[LITTLEWING]

I've just acquired a used Squier Standard PJ four string with the Jazz neck, thing is the original Jazz style bridge pup has failed and there's an Aria unit in it's place but it seems a little quiet compared to the precision pups even when raised nearer to the strings. When both volumes are up it's even a smidge less. I've seen a couple of Wilkinsons on the 'bay, one's 7.5k and the other is 9k so which one would be best for balance with the original split precision pups?
