MSBS, might not be perfect, but it is still better than DFRDB if you are going to leave early.
Only problem is when you do leave, the notional money that the government has promised to pay into the fund for you, but hasn't done so yet, only grows at CPI. Although that outperforms the fund at the moment, it is not a nice way of saving for retirement. It would be far better for us if we could take the money, and put it somewhere that it would really get to work (like on red at the casino!).
Hope the flying pay thing works out. But that rumour has been around for sooo long, I think it is dead in the water.
