Here is a little more reading on the switch rod:

The term “Switch Rod” was to the best of my knowledge first used by those that favored the 60s vintage Fenwick 11′ glass rods for delivering either up sized floating double tapers or built-up grain weight forward lines… Utilizing deliveries similar to what we now call “Turbo Spey” (single hand spey), and conventional single hand roll cast and double haul overhead presentations.

And indeed, Fenwick did actually have a removable lower grip assembly available on a few of those early rods. To my great pleasure and suprize, A fella brought one of these beauties into my shop last week, and I will have a chance to fish it on the Rogue with him in the very near future !

Hardy too had a series of 10′6″ bamboo switcher style rods that predated the Fenwicks. Again, one of these came to my shop late last winter by an angler that had it custom made for him while stationed in post war England. Very fast, with a stationary lower grip. An awesome shooting head rod for underhand spey or two handed overhead presentations…Although a bit heavy for most mortals to cast all day utilizing single hand deliveries !

There surly are other rods out there that over the years were designed with the same intent.

John from Rio calls my 106ers “Hand and Halfers”.

I do also like the term “Three Handers” used by Great lakes anglers that Jr. Spey mentioned !

My series of switchers includes rods with single/two handed capabilities from 9′9″ to 11′4″ in line weights from 5/6 to 12/13…For both fresh and salt water applications…The shorter rods being shooting head specific.

What ever the term used to describe these rods, regardless of who made them…Once used…Their diverse capabilities as effective angling tools quickly become apparent. Plus they are all great fun to use.

There is quite a few different people and companies claiming to have started the idea of switch rods.  Pretty interesting.
