Take a look at the DynaPlug Racer. All my roadie friend swear by it. I just ordered one myself.

I love the Dynaplug. You can be back on the road in two minutes or less. I've used mine 3-4 times and it has worked every time. I rode a Schwalbe with two plugs for several hundred miles. My experience is that it is almost always a fix good enough to get you home and usually good enough for a permanent repair.

Thanks both, will give it a try
