I started fly fishing when I was 7 or 8. The rod size depends on how big he is, I would recommend a 9' 5wt that is NOT a fast action rod. The reasons I would hesitate to go lighter is the fact that he will get more use out of the 5 down the road, and the slightly heavy rod is going to be a bit tougher... less likely to be broken. As long ad the kid is strong enough to do it, age isn't much of an issue.

I was started young, and taught right, and because of this I can cast exceptionally well now. I'm 28 and have already been fly-fishing for 20 years... Starting young and right makes a big difference down the road... Think Tiger Woods...
