That'd probably be a Presta valve. Yes they seem to be prefferred. However I
have a Schraeder adaptor on my Prestas. The only reason for that is that my
CO2 pump seems to fit better over a Schraeder than a Presta and I lose less
air when filling. I don't think whatever valve leaks will be an issue, for
me anyway. I always pump my tires before every ride because I want to know
exactly what my air pressure is and any valve will keep air long enough for
that. I'd say whatever kind of valve you use will be up to what kind of
pumps you have available and how they fit.

Hum... you are right, I did not think about that. Ok, a backup repair kit
as well then to use in extreme emergencies

Only $33 per tire? There's plenty of various sturdy 700X30ish tires on the
market, often on sale, for 10-15 bucks. I'm a tightwad, but $33 for a
"commuting" tire seems outrageous, I'd understand a premium for a
high-falutin' racing rubber though.

BTW, I've not carried a spare tube in over ten years, just a patch kit and
some duct tape and one tire lever. The only tubes you really can't patch
are when you get failure around the valve--so file those rim holes smooth.
.........Knock on wood I find patching faster than replacing a tube
since I just leave the wheel on the bike and pull out the few inches of
tube that are affected. I rode a Sturmey Archer Raleigh and a Nexus7 for
many years which explains my disdain for wheel removal, even though I've
got qt hubs now. LOL

that's good advice, though I do find presta easier to inflate, you can
always carry a little brass adapter if you need to use a non presta pump.

Air loss is usually due to the porosity of the tube itself and not the
valve--usually
