Some reasons:
More prone to damage during install (especially if you use C02)
Greater chance of flats
Higher cost

Whether or not those override the weight savings is up to you. Being cheap and not a weight-weenie I don't bother with them

Get latex tubes. They are more porous and bleed off air pressure faster, but I air up my tires before every ride anyway, so it's not a factor to me. The lite butyl tubes flat WAY too easy IMO. BTW, I only use the latex tubes on my "good" wheels. Use regular, heaviest as I could find, $2 a pop, butyl tubes on my training wheels.
Thank you nmtreeman

Define light weightKerry

I use the Michelin Ultralights and have no problems with durability or tube failures. That's a 70g tube. They loose about one bar pressure in a week, so there's no need to pump them more than twice a week. These tubes can be easily patched and the smooth valve stem makes for a really good seal with the floor pump. List prices is $6 but they often go on sale, and they last for a couple of years, at least.

I am presently running a 200 gram tire and Specialized ultra light weight butyl tubes, a really light combo.

The benefits are less rotating weight and I can feel it, too.

The tubes need to be checked before each ride for pressure as they lose air faster than regular butyl tubes but I checked pressure before each ride anyway so no real difference there.

Very exciting while descending twisty roads and the front tire suddenly goes on you. If you want to live dangerously make sure to buy Lunar Lites from Performance and keep your health insurance paid up. You'll also need to change your shorts.
