baitcasters(levelwind) - cast left handed, reel right handed = no hand switching
centre pin - cast left, reel right (fish a Silex so it is only right hand anyways) = no hand switching
spinning rod - cast rigth,reel left = no hand switching
fly rod - cast right handed,reel and strip lefty = no hand switching
spey rod - cast with both hands and reel is setup for right hand retrieve = not really much hand switching depending on river direction.
when i started fly fishing especially my reel was setup right hand reeling and i found that i lost fish trying to switch hands either missing strikes right after the fly hit the water or when the fish got slack while bringing it in
I find im on the ball alot more when i dont have to switch hands. even when drift fishing i have caught fish almost instantly when it hits the water and also the fact i can start controlling my drifts instantly because there is no hand switching.
just some food for thought
