Haven't  ever  ridden  many miles on sewups, I can't  speak for them.  I
have ridden quite a few miles on Specialized  Touring II's (1") and have
been fairly happy with them.  As soon as I get my second flat on a tire,
I generally throw away the tire because my experience has been that once
flats start occurring, the tire has lot a lot of its rubber.

In the case of clinchers,  the tube is also very  important.  I'm fairly
heavy (185) and ride  standard  tubes.  Some of my heavier  friends have
tried some of the higher performance lighter tubes, and they seem to get
more  flats.  Some  of  my  lighter  friends  (women   especially)  ride
Ultralight tires and tubes, and have no problems.

I recently  bought a new bicycle, and debated whether I wanted  tubulars
or  clinchers.  I decided  on  clinchers  for 1 main  reason - easier to
repair  on the road (at least for me  anyhow!).  It seems  like a lot of
triathletes  and bike racers  around  here train on  clinchers  and ride
tubulars when competing.

I agree that sewups are not just for rich nutcases.  I have two sets 
of wheels, one sewup one clincher, which I ride about equal mileages
(~150 a week).  I have lots more problems with the clinchers.  The 
sewups are lighter & more fun to ride, give a better (more comfortable)
ride, have much better grip, and flat less (no flats in a couple 
years).  I hypothesize that this is because they are better made: the 
casing is more flexible, giving better ride and grip, while the tread
is much harder rubber, giving better wear qualities and glass 
resistance.

This view is a little biased, because the sewups are a well-aged pair
of Clement Campionato del Mondo Seta's. The clinchers are Specialized
1 1/8 inch high pressures.  Does anyone have an opinion about the 
folding clinchers?

I still ride clinchers because they are better for touring: easier to
repair in the boonies.
