I have arthritic wrists and elbows and graphite shafts help, but need very soft feeling irons. Are these irons considered soft feeling?

I realize the controversy about forged vs. cast. I have hit forged clubs with graphite that hurt, especially on mishits. I now hit Cobra Amp Cells which are cast but never hurt. The ST-I irons intrigue me because of the narrow sole which I like because I am a picker.
