I think the above did mention, digital stringing constant pull or something, coupled with my assumption that if I told my chef I would like 28lbs, he'd do what he knows best and deliver that feel. And if you think you are playing at what the stringer delivered at 28, with the job a particular stringer strung, then honestly we're pretty much done. I like to think of a stringjob as a more emotional feeling thing than say, a numbers game. Chef A's 28 may not be what you like and perform best compared to Chef B's 28. I know of smart alecks doing/asking/trying 28x30 because the "cross is +2 of what they want", or 27x29 because the tension when the strings mate in the middle happens to be *drumroll with gasp* middle ground 28! Holy crap are they genius! Say, why not let's do 26x30? Middle ground logic!
