I've had less problems with flats after I started deflating the tires at the end of the day.
Also, I rarely run my S33 Specials (tubular clinchers) at anything greater than 120 psi unless I'm on a paved trail where it is less likely to come across glass or metal shards. I rode them for 62 miles on the road (littered with glass and other crap) yesterday at 120 psi and this morning, commuting, at 100 psi in the rain--no problem. I haven't been using the sealant until I absolutely have to.
You can seal exterior cuts using Shoe Goo as long as you haven't used Tufo sealant. YMMV using Shoe Goo for punctures.
I've been able to fold a spare S33 Special tight enough to fit in my jersey pocket along with a tube of sealant (just in case) and small plastic box that contains spare valve extenders, valves, and Tufo valve removal tools. My jerseys are men's small.
