I confess I am a mixed bag of nuts when it comes to fast and slow rods. For my trout rods (for example) I have two, and the one that bends to the cork gets used way more than the one that is "whippy stiff." For double haul casts, the stiff stick just plain sucks. Maybe a wolf ambush line would get it rocking, but I trout fish so little, it'll be a while before I try another line. For the long rods, I have to say I am in love with the faster sticks. However, it really is only the butt section that is stiff ("tip flex") and so maybe it's really a slower rod with a stiff extension... The first switch I bought is definitely full flex, and is replacing a much faster single handed rod that was being used in a switch capacity. I like the fuller flex of the switch. Like I said, mixed bag of nuts.
