I take that on board, but still pose the question. Is it the BEST option, a 20" bar will handle some damn big trees and be a lot more handy into the bargain. I question the true need for many big bars in the first place, sure they look good, I won't deny that, but they cause more friction, upset the balance of small saws and, unless your storms are a lot more orderly than ours, pose a definite hazard when working in close quarters, simply getting in the way.
For many years I ran a 55cc saw with a 20" bar - something I would never do now as I learned that 55cc = 16" in our hardwood to be truly happy. Based on our timbers 20" is 70cc territory 28" is more like 85-95cc, I realise that your timbers are different.
It seems that many people believe that longer bars make the saw better, in a great many cases they detract from the performance.
End of the day, if someone want's to run a 28" bar on whatever, that is their choice, however I would bet that the same saw with a bar more commensurate with its size will outperform it and be more pleasant to use in to the bargain.
