Sloppy, I agree with Johnny. I've spent a lot of time doing the maths on this one. I am lucky enough to be leaving to a very good salary and another final salary pension scheme. I could probably just let my pension payments build up in an investment and not miss them too much.
Having said that I am booked in to see an independant financial advisor to look at all my options and I recommend that you do the same (I'm sure you would anyway).
