The 27 is quicker than the 28 is currently, that is enough for me.
Because the 27 was faster in Australia without developments last year than the 28 currently.
At no point have both cars run together, so no comparisons can be made. The times in Aus from this and last year are not comparable because of the differing tyres as well as the conditions in which quali took place.
And surely it will be a lot better to try the 27, it could go two ways, 1, it fast out of the box with the new tyres and just needs updates. 2, its slow by a second or two and would need a lot of updates. but the 28 is also 1/2s slower already and sounds like it will take a lot of updates and even then it could still have a lot of other problems.
If its not broken don't fix it
Trouble is the 28 is in a developmental cycle, with updates planned and in the works. The 27 has a differing philosophy to the 28 so they'd have to scrap everything they're doing and work on updates for the older car. Not to mention whole new chassis would probably need to be built of the 27 as I don't imagine the ones from last year are as pristine as they were.
Edit: I did say at the bottom of my original post that McLaren would have better to stick with the 27 and evolve that concept ;)
Scrapping a car for the sake of it won't happen, Ferrari had the same calls last year and McLaren had the same calls in 09. They won't do it and will persevere with the 28.
