I never got on with SRAM double tap. I stuck with it for about a year then gave up and sold the bike as, cost wise, I didn't think there would be much in it between that and changing the groupset. I would say you know more or less at once if it will work for you. If you don't "get it" in the first 100 miles you probably never will.
