Very interesting thread this....
Haven't had time to read it through in detail but I would chip in that 65m for 30 min is not really viable. You don't have enough back gas (unless you both have a set of twin 18's perhaps). With twin 15's it's too marginal. And with twin 12's it's a no-no.
Also, the run time is a bit more than I'd be comfortable with in UK conditions. Without regurgitating all the details, I'd probably cut the bottom time to 25 mins, do the deep stops and end up with 3 at 12, 7 at 9 and about 15 at 6 (a RT of about 100 mins). Gasses would be 15/55, 50% and 100%
Cutting the BT to 25 mins would keep everybody happy according to the deco progs.
I would add that this sort of dive planning shouldn't be copied or mimicked from anybody else. You need to find your own comfort level and do the deco YOU are happy with.
Jez and Michael would freely admit that their problem last year was caused by not following this advice.
It's not a race or a competition, despite what some people might tell you.
