I've tried both and like a short one better. How long you talking about? Too much rod length gets in the way for me, it's much easier to handle a short rod. And, the "rubber band effect" is the same with a short rod. JMO
IMHO, Short for sure but brand makes a difference. I started out with a 4 1/2' MicroSpin and it was like a willow limb. No control. I have the Pro Angler 4 1/2' now and it has the most backbone of any light action rod under 6' I've ever used. Excellent control shootin' docks.
