I alternate between a variety of rods as it's cruel to have a favourite to the exclusion of the others.
For smaller waters I use a Marksman supero 10' bomb rod and dare I say it's bombproof and a delight to use. For slightly larger waters I use a Marksman supero 11'feeder or à Supero 11'6" Avon both of which are delightful. I also use an Amorphous Whisker 11' to 13' feeder which again is a lovely rod. I have yet to use it at 13'.
For iffy waters, inclement weather( read wet, muddy and b***** horrible) and overgrown rivers( one was so overgrown I couldn't find it) I use the DV .75 Avon which is a lovely rod and a snip at a little over £40.
I like to change them and they are all unique in their own way.
