Bunk or Roller Support?

Boat = 1980 Outrage
Existing Trailer Setup = 100% weighted on 4 2x4" bunks (2 shorter bunks on the outside and 2 longer on the inside)tandem axle
I read some previous posts discussing 80% of the load should be on the bunks and 20% on the rollers. Is this correct?
Any suggestions how I should rig the trailer? I am getting ready to replace the boards (upgrading to 2x6").
Thanks for the input.

I don't recall any citation of an 80/20 division of weight between bunks/rollers anywhere. Can you point that out to me, as I'd like to be sure to make some comments in that thread.
For years Whaler factory recommendations were for keel roller trailers only, but more recently they joined the industry trend to all-bunk trailers, at least in permitting them to be used under their boats. I don't know that they recommend them.
If you actually buy a trailer from Whaler (from CPD) it will have keel rollers that carry most of the weight and small bunks to lend lateral stability.
Only the newest package deals in the last couple of years (13 and 17, oops make that 130 and 170) have had Whaler boats on factory delivered trailers that did not have keel rollers. And these are small, relatively light boats.
For years Whalers were sold by dealers who decided what trailer to use under them, and as a result there has been a wide variation in what can be found in use.
We've had hundreds of messages on this topic, and many long articles in the REFERENCE section. Everyone likes the trailer they have now, I guess.
