To be honest Kev - I think there is a bigger question. You are 38 - are you happy staying in your current role (or moving with limited flex in the PS) for the rest of your days - 30 years - or would you prefer to change role and think you would be more fulfilled in another role? I have faced a similar situation, and had to ask myself if it was worth 30 years of a compromised career and less job satisfaction for what might be a bit more in a pension (if I am healthy enough to enjoy it, touch wood!)
I would notl et the pension be the deciding factor here
