I have to say I havent noticed any change in trajectory (dynamic gold s300 (firm to stiff shafts) they are great irons in my eyes and not just because I own them, looking down they are not too big or too smal and the top line is just right. As far as distance is concerned, I have also not noticed any loss in distance, if anything the seem to go a certain distance more often rather than some long and some short, possibly the shafts as I was using rifle 6.0s previously on my RAC LTs.
