Chris/entwood, if you two are meeting tomorrow I would like to hear your feedback on the Eagle F1. Should be run in by now. 
They've done about 500 miles, but a lot of that on ice/slush/rain/generally poor weather, so I've not been pushing them at all. I still have a small problem with the steering box setup which is making the selfcentreing "not quite right" .. another 1/8 of a turn tomorrow...

What I can say is they are quiet, seem to move water well (I've driven through enough of it !!) and on 2 occasions when idiots have forced me too, the stopping distances have been very good, on one I was very surprised the ABS didn't go daft .. but they stopped very well.
Chris is going to have a try tomorrow, to see what he thinks of the steering box, the tyres, and the before and after effects of the poly-bushes.
As he knows a lot more than me we should be able to give some comparative opinions !!
