Whats the best of the best for front suspension on my 2013 Ultra. currently I'm running heavier than standard SE oil but otherwise original. It's "ok" but I'm sure there is much better for our shitty WA roads. Any suggestions appreciated.

Coupla grand is in the budget but for $10k I can buy the missus a street 500.

Let me know how the cartridges feel. I might go that way if they meet up to your expectations.
