Being rather tall 6'6" ~ 2m, I have been subject to back problems on and off. I found the best solution to my issue was the gym. After going to the gym for a few months, my doubles were not an issue. I now have the core strength to handle the stress. My RVM improved a great deal also (not to mention quality time with the wife.).

Now that I've been diving CCR I only use my doubles as banks or drive gas. I'm sure the long term load of doubles does damage to anyone, but SCR/CCR is not the solution to the problem, just a solution to the symptom.

FWIW

PS. Classic Kiss 52 lbs. Much lighter than my double 120s.
