Short, medium-short, semi-average...
Having fished small streams with rods from 6' to 8 1/2', I don't think that the differences are noticeable, except near the margins. If you want a high-performance stick for the needs you list, consider one from 7 1/2' to 8' 4". Then you might want to add one for really tight little streams; something like my 6 1/2' built on a low-modulous Lamiglas graphite blank. There's simply no need to pay for any high performance parameters for this shorter rod.
