I fish a 6'9" 1wt in those situations. Its a custom, built on a TFO Finesse blank. Got a Sage DT1F line on it and after fishing small streams with a 7'9" 3wt and a 7'0" glass 4wt, I'm convinced the light mod-fast graphite 1wt is THE rod for small streams and trout under 14".

I don't really like the glass on those truly small streams. The soft slow action requires lots of room for back casts, which you simply won't have.
