Hi I have been using switch rods for about 3 seasons now, I started with a guideline 11' with a Beulah switch line. but got the option of a Batson 10' 6" kit which I built up and that suited me better than the Guideline until I found the reason why, I have long arms and the Guideline butt was a bit short for my normal grip space so last winter I added a few corks to the top and it was much more comfortable.
Most of my switch rod use is on the South Esk and nearly always for Spey casting, this year with the low water the fish were still coming in but only lying in the deeper pools, I was using the Guideline with the Beulah line and getting nothing. I realised that the Beulah line is bright yellow, despite a longish cast and a clear braided leader. A change to my Batson with its blue Airflow head saw me connecting with fish. The Beulah had a waterproof felt tip pen over it when I got home!
But I digress, the switch rod is a favourite of mine, especially the little Batson a great wee rod that cost me £120 for the kit , you can cast all day with nominal effort, its ideal for the smaller salmon and sea trout rivers where tree cover means roll or spey type casts.
