I cast & fished this rod at Haddo today with the GT140 #3 line and was very impressed, it fished like a 3wt but cast like a #5.
More than enough power low down in the rod to lean on and turn a big fish but, without feeling stiff or pokerish (as much as a 3wt ever can), superb feedback from the blank. In terms of casting it will throw a long way when strung with the GT line, I was able to carry over 85' and shoot a lot further yet at close range it was superb too. Short quick casts and direction changes to cover cruising fish with a single dry were effortless and required no thought.
If you like light line gear it is well worth cast next time you are at Haddo, think Mike will have the demo rod most days.
Cheers
Ben
