Well, I think there is truth to both sides of the low timer argument.

I love the experience gained by CFIing. I think it's valuable not only for flying skill and experience, but (more importantly) thought process. However, that being said, not everybody is cut out to be a CFI. They may be phenomenal pilots, with impeccable knowledge of regulations and a profound understanding of the industry and its workings. But they couldn't teach a student to tell difference between the brown half and the blue half.

That's not to say that there aren't other time building options.

With regards to the argument between low time pilots and high time pilots, well, I think it's a pretty inconsistent argument. Yes, there are way too many 250 hour pilots out there flying jets around calling up even the most uncongested airport with "Uh, Waterski, um, 3....325, uh, outer mark...er outbound....INBOUND", and there are plenty of low time (maybe not 250 hours) pilots out there who are perfectly capable and are skilled and dedicated enough to learn their stuff. There are also plenty of high time pilots spread across the same spectrum.

I'm of the school of thought that the problem doesn't necessarily lie with the incompetent 250hr pilot who accepts such a position, but rather the interviewing, hiring, and training process that does not adequately screen and weed. Rather than asking the same 25 technical questions on an oral (gouge?), why not have a couple minutes of more complex ATC dialogue? Rather than a sim session where a pilot flies a single or twin engine Frasca, why not put them in one of the airline's sims for half an hour and see what their learning curve is? Find out about the person's personality. Why even bother with all the stuff that can so easily just be put on flashcards and memorized and forgotten after the interview (what level of learning is that, CFIs!)? If I can remember what cities that an airline serves, domiciles, company officers, company history, etc etc etc, don't you think that I can remember when runway edge lights change color?

I guess that I've seen so many good low time pilots, bad low time pilots, good high time pilots, and bad high time pilots, that I don't believe in the Holy Grail of having more and more hours. It helps, but it doesn't make or break the pilot.
