I tell you what, My M400 1 flat from a OLD tube in over 1000 miles.
My T700 with $12.99 Forte Gothams no flats in 900 miles
My R600 that I hardly ride I have had 3 flats in 100 miles and ALL three the bike was in the house and I was pumping up the tires when they happend.

1. leak too close to the stem to fix.
2. broke the thin stem on the valve.
3. hole too close to the stel to patch. (it was the other rim and this tube did not have the threaded stem and that was part of the problem).

Now the good thing was flat number three was last night when I decided the bike needed to be rode to work today. Well I did have a spare tube so I fixed the bike last night but since that left me no spare tube I decided not to ride it. Good thing as the DOT decided to run a pavement grinder down a stretch of my route today for about a 1/4 mile where they are adding turn lanes both directions. I nearly rattled my fillings out on the 700 x35's I would have had to get off the bike if I had hit that on the 700x23's on the R600. Hopefully they will get it paved tomorrow before my ride home. My ride the sidewalk around it or ride my mtb tomorrow.
