Don,
With .024 it will need to be a 14 strand (maybe more) string with D97 to fit the nocks on carbons.
I use D97 in my strings 12 to 14 strands and .030 Halo. Seems to fit the GT nocks well.
You can also pad the serving area. I don't care for the fit or finish when I tried padding in the center of the string.
