I've ordered up 9-footers, since I have both an 8'5" and a 9" 5 wt,
and I find that I can cast more easily with the longer rod. But a LOT
of websites mention 8'6" 5 wt rods as the best beginner rod. I was
thinking that the shorter rod might be less versatile for the kids.

What do folks think: what are the advantages to one length over
another on a medium-fast rod? Should I change my order to 8'5" rods?
