I was at exactly the same point two weeks ago after around a month of nearly buying. In the end I went for the kenda combination (BG & Nev). They are amazing tyres when it comes to grip. Way way way better than the MK's I ran for almost two years. Don't get me wrong, I liked the MK's (2.4's), they offered a good compromise of grip, speed and puncture resistence especially pinch flats.
But grip wise the kenda's p**s all over them. Speed wise they're a little slower but not too bad, nothing sapping like. The only issue I have is that they're really not great for puncture resistance. The first weekend I had three pinch flats and one puncture. I'm still playing around with tyre pressures but I haven't struck the balance between being soft enough for grip and stopping punctures yet.
Depends on where you ride though, I live in the north west and so ride in the lakes a lot and such like.
