With 40 years of casting, imho, longer rods tend to suit less experienced casters personally I find the extra leverage tiring and line control and speed of fly control slow, yes you can lift a longer line with ease, but if you learn how to switch roll, you can roll a full line up off the water, even when deep wading with a 6 foot rod, thenre cast the full line with no false casting to the desired spot with ease.
Longer rods are also more expensive and less accurate to cast with ,sorry but I think you need a casting lesson!
