I decided to buy one Schwalbe smart Sam plus for my Typhoon. I stuck it on the rear since that's the hardest to fix a puncture if you need to take the wheel off. I've done about 100 miles with it and must say, I like it. It rolls smooth and more importantly, it's quiet. The standard tyres whine like a turbo when on smooth tarmac. Now only the front makes a noise. A second smart sam plus should take care of that next week.
