Into the Water

Hi
Would really appreciate if some body with good deco theory experience and deep air diving help me to analyze few dives. And write some arguments.
How safe would be to dive same dives in warmer water in term of DCS? What was main mistake on diving that kind of profiles? Could be DCS be avoided with diving same profile in warm water or with longer deep stop 80%, 50% and shallow stop 20 feet and 10 feet?
Diver maid two dives:
Water temp 39-40 degr, surface interval between dives 1:42, Gas 21%
1st dive: Depth - 124 feet, Avd - 66 feet, Dive time - 33min, dive profile below.
2nd dive: Depth - 119 feet, Avd - 63 feet, Dive time - 34min, dive profile below.
Second dive was finished 5:15pm, about 8:30 pm diver started to feel DCS symptoms: joint pain in left arm shoulder and elbow, numbness in fingers, overall weakness and fatigue. Early in the morning he was delivered to hospital. Report from doctor: DCS type 2, Table B6:a 5h
0 - 18 m
21% O2 10 min
18 m, 70 min:
100% O2 20 min x 3
21% O2 5 min x 2
18 - 9 m
100% O2 15 min
9 m, 210 min:
100% O2 60 min x 2
21% O2 15 min x 2
9 - 0 m
100% O2 30 min
VAS 4 - 0.
Not allowed to dive for 3 month
same evening symptoms came back but much less
next day again treatment 2h
Max depth till 14 m
100% O2.
21% O2 5 min.
Stopp på 9 m 10 min.
Stopp på 3 m 3 min.
VAS 3-0.
T Diklofenak 50 mg x 1 and later one more time
1-1,5 month later, sometimes still feeling joint pain in left arm elbow and shoulder.
Please avoid useless speculations. I need only arguments and maybe it is still possible for me to change few ego sick divers from future mistakes.
My own opinion don't dive below 100 feet on air it's 2017 already.
