I often use a 7' 6" #3 Greys GS2 for small river fishing, it has a lovely soft action. I think they do a 9' #5 or an 8' #4 too.
Ive also just bought a Loop yellow line off here for use on larger rivers. Its a 9' #5 but has a nice soft action too. Took me ages to find one, they dont seem too common.
Also have an original model Greys streamflex in a 9' #4. Its not as soft as the above but still much softer than most rods.
Or you could try and find a fibreglass rod, most seem to be fairly soft actioned, Ive got a 5' #2 Hardy Aln and it has a very soft action. They do an 8' #5 too.
I dont really enjoy using fast actioned rods.
