Of all the springers my tuned 95 is a pretty light weight in the cocking stakes. I suspect only my Sports are as light.

Shoulders and spines often sort themselves out, but take yonks to. My issue is my lower back, and had that issue for 25 years. Last time it went pain ballistic, rather than operate as before, it was a year of grief and pain management. Kind of eventually sorted it out though anything active has back preservation as a priority. Taking off weight and doing strengthening is part of the management plan. Still it takes little to set it off.

As suggested, do a year PCP break. Then try again with your springers. Only then decide.
