Tom,
Just for info, tried my new suit on Saturday (It turned up

). The autodump is in exactley the same place as yours and with the Sitec autodump it seemed to work quite well.
The sitec dumps seem to dump air better than the Apeks low profile valves although I did find I have to tilt a bit more than I did in my old suit. But at least it does dump easier.
YMMV
Daz
