Re: SLOOOWWWW action graphite rod?
I am personally not in the deep flexing camp of rod actions, however, we did have a new Circa 8'9"/#4 in Camp this past month. It is super slender, handsomely crafted and as deliberately slow-stroke timing a rod as I can imagine yet remain presentation functional. It is no wimp, it can cast with some authority albeit not at distance, its has personality and quite a bit of charm. As others have opined, Scott's long standing G/G2 series of rods are deservedly beloved for their deliberate yet usable gentle touch and also very well built. Among older rods; some early T&T's and Diamondback Classics were quality carbon rods with slow actions. And, though their recovery rate may be slower yet do to increased mass, fiberglass remains a great rod building material for shorter, slower rod applications. The greater mass of the glass contributes to its in-hand sense of flex similar to cane.
Slow action, deep flexing rods can be fun for swinging a soft hackle caddis pupa or aiming a dead drift nymph to a visible sub-surface feeding fish on a gravel bar but if you hope to generate line speed and tightly controllable loops for reach casting and in-air line mending to alight a dry fly with precision in a bank feeder's lane a more progressive taper with a quick recovering tip is far more responsive.
