I have a 74lb MK on my 2002 classic, and I wouldnt want anything less than that. Mine does fine most of the time, but it dissappoints sometimes when Im fishing in current. Overall, its not enough of a problem for me to upgrade, but I defintely wouldnt want less than what I have. I would think that 56 lb would be underpowered also.
