I have a medusa and use it for general course work especially canals. I have only used it at 16 mtrs twice. At this length as with most 16 mtr poles it is fine for an hour but after a 5 hr match it becomes heavy. As most of the canals around my way are 12-13 mtrs the medusa is great. I have compared the 711 to the medusa at Nathans tackle in Derby, both handle similarly at 13 mtrs and the 711 is only 14.5 mtrs.The Medusa spares are cheaper than the 711 and that extra 1.5 mtrs does come in handy now and again.
