Other then the Tour 90 being a little lighter in weight you might not see much difference in trajectory with these two shafts. They are both listed as mid/high trajecotory shafts which is normal for lighter weight steel shafts. The KBS Tour 105 (FS0041) tests stiffer then the XP105 and that could give you a lower ball flight. You will need the .355" taper tip shafts for the Mizuno MP HP irons.
