Dougie, I did not wish to antagonise Aeroid by mention of the J. Or the square window as Smudge referred to it last week.
In my day CADS only went to 350 lbs (may have been 400 with the French Square chute). We never got the French chute in what we called the Duplex bag which could be rigged for Freefall with the old Irvin Hightfinder so it was only Static line for HAHO.
I too spent a lot of time over the years at YPG with various crews. I used to sing a little in the Sage and Sands or Pop the Top. We also did stuff at El Centro and China Lake. We did the CADS Mk2 trials at CL in around 2002.
