today i use 40/85 working ok for me.. on normal dives.. and use for below 50 mMany people are reluctant to give such advice since everyone has differences in physical shape etc.
I use 60/90 unless doing deep or very long dives and then I use 60/80. I am about to go more conservative (60/80 and 60/70) since I am getting older and do not wish to get bent again.
