Take pension now or wait and get same pension + RPI

I can take pension at £3.4k/annum DB now increased at trustees discretion (2-3% annum maybe)

If I wait a year I get £3.4 + RPI /annum (ie) say 3.4 + RPI UK = new amount and from then on increased at trustees discretion (2-3% annum maybe)

Same process for next 5 years until 65

Pension is part DB and part DC
Current situation is £3.4k/annum + Tax Free lump sum + £1.6/a from rest of DC part. (this figure from last March so awaiting new figures which should be better)

So exchange rates & stock market risks exist.

Question:

Is there a real monetary advantage in putting off the pension for a year and getting £3.4 + RPI /annum next year (RPI was % in UK last year but will be much smaller this year)

Or should I start taking it now?

Thx in advance : M

Is this a dumb question with the answer - "go see an financial advisor?"
Cause I cant figure it out.
Any help or opinion very welcome.

UK question? I am always in favour of getting the money as soon as possible, as you usually have to live longer to reap any benefit, and most of us are not that organised.

thx for the opinion G. )
