I switched to Bohning Accelerator wax last year. No build up and works super easy into the string.

I just put on new WC string/cables on my Vulcan and am now using the WC string conditioner. It feels very similar to the Accelerator wax once on the string, but is dry to the touch before you rub it into your string/cables. I like this much better than the Accelerator for that reason.
