That seems reasonable to me. My 7 iron is a 160 club. I carry 9-5 in "traditional" irons. I carry a 3 and a 4 hybrid. 19.5 and 22.5 degree respectively.
BTW - I had to answer neither in the poll. As I carry a 19.5 degree and 22.5 degree hybrid. So I have nothing that fits the 20-22 degree description in the poll.
