Yea, I don't use HD tubes either. Never had a flat - ever. I don't
buy the whole theory anyway - if something is nasty enough to punch
through or squash flat a 1/2" thick tire carcass, do you honestly
think an extra couple of millimeter or two of squishy tube will make a
difference? I don't. Can't comment on the valve stem thing - it
sounds like you're not reefing your rim locks down tight enough to me.

There certainly is a considerable difference in the weight and feel
between the heaviest tubes and the normal thin ones. I've got one
fairly old super heavy duty tube that has been in and out of use for
several years now. It's scuffed and had little rubber balls all over
it, but still going strong. A standard tube would probably have holes
in it by now?
Which is better... I don't know?

Maybe yes, maybe no. I think I only changed a tube in my XR once
since 1998, and I got whatever was the cheapest at the bike store. I
think one of the tubes is OEM.

Keep in mind that many of these guys actually ride their bikes now and
then. Once upon a time I did too.

Sir, I am in violent disagreement.
I've been running Ultra heavy duty for 20+ years. Never had a problem. By
chance, you wouldn't be removing the lower lock nut that holds the stem in
the tube (some versions), would you? I tried this exactly once. The stem
came loose.
Another tip for longevity: coat said nut in anti-sneeze to prevent
corrosion.
On any tube, you should never tighten a lock nut on the valve stem. I use
those Honda rubber grommets, & lightly set a lock nut on top.
I ride with some fairly large groups in Utah. Every pinch flat I've seen
has been on standard tubes. Most of the guys ride with heavy duty tubes.
The minority with standard tubes accounts for the majority of the flats.
Yes, they weigh bit more. However, they allow me to run lower pressures to
maintain better control. Even if you notice they slow you down a bit, the
slower rider will finish before the guy who has to fix a flat. Not to
mention flats take away valuable riding time.

I use this rubber thingy and the valve cap as locknut... No steel nut.
I use rim locks, without them, you can rip the valve stem easily.
Never ripped a valve stem while using rim locks, HD tube or not. More
often than I like I hit a nail, then, it doesn't matter if tube is HD
or not.
