I own and fish two 16' rods. A T&T 1611-3 that I fish with a long-bell line of at least 870 grs (the WA/FF70 10/11), Vector Gen 1 tournament line (75' belly 950 grs), Gen 2 Grandspey 9/10 (1100grs 85' belly), and similar work well.
A Meiser 16' 8-10 is the other 16'' rod that I fish with a Gen 2 Grandspey 8/9 (800 grs, 80' belly), WA/FF70 9/10 (750 grs, 70' belly) and similar.
And the big gun, a G.Loomis 1812 that I fish with a Gen 2 Grandspey 10/11 (1200grs, 90' belly) or better still, a tournament line that weighs at least 1150 grs with a 90' or longer belly)
I'm seriously thinking about getting a Meiser 16' 6-8 and a 17' 10/11.
