Well, I figure that since your from the Huntington area and your cutting firewood, that means your not cutting pine.
So yeah I figure that the 28" would be givin the ole 700 all she wants and unless you have a line on a bunch of big trees, the 24" would be better suited for it.
Ask yourself, are there really that many big trees around you that you can't get through both sides with a 24"?
If you do run into some you can't get through with the 24 then you have the perfect excuse to start looking for the 80cc or bigger saw to run the big bars.
