I am in the process of building a new home and have heard some disturbing remarks on the inefficency of the now so popular, easy to install flexible ducting. Just what are the pros and cons...and is it worth it to go with the solid smooth bore?

If you mean HVAC ducting, I don't know, but I recommend smooth vent duct for your clothes dryer from experience. I removed the one in my house last year because my wife was complaining that the dryer was taking forever to dry the clothes.
I was shocked to find that the flexible plastic vent was nearly clogged with lint. I replaced it with smooth metal. Mine is in the crawl space.
Unfortunately, some people can't do this, as the vent is run inside a wall when the house is built and you'd have to tear up the wall to replace it.
If you can, you should have the dryer vent in your new house done with smooth metal. It will not only save $$ in clothes drying costs, but also reduce the chance of a fire. Clogs of lint have been known to catch fire.

Air is slowed down quite dramatically if it is forced through a rough-surfaced conduit like flexible ducting. The air will tumble through the duct, causing high pressure pockets. The net result is that the air that you are trying to expel will slow down and, sometimes, not make it to the end of the duct. In short runs it can be tolerated, but long runs of flexible ducting are to be avoided. Using 3' of flexible duct can be equivilent to using 30' of smooth duct.

When the pressure builds, your fan will have to work harder to push the same amount of air through. All in all, it is very inefficient both from an energy and air flow standpoint.

Hope this helps.
