I think your going to be all right, as you have "Grandfather" rights.
May be worth a letter to the pensions board for clarification though
I expect, although several years to go until my IP point, that I should attract exactly the same deal as yourself, unless "They" come up with devious schemes to get you to sign away the "Right". Just as they did with JTs following fitter courses in the 80's with their time promotion to Cpl. Too many good muckers lost at the 12 yr point with that.
