Caster2,
No simply because I bought a T&T 1611 (16 ft 11wt) 7 years ago for winter steelhead, chum salmon, and chinook salmon fishing. I wanted a rod with even more power and a bit more length than the T&T 1510, which is why I bought the T&T 1611. I use 11 wt RIO sink tips of type 3, type 6, type 8, and 11 1/2 ft of 700 Grain SA Deep Water Express on my 16 footer.
I have a very good friend who owns the T&T 1510-3 (3-piece version of the rod you mentioned) and he fishes 10 wt RIO sink tips of type 3, type 6, type 8, and 14 feet of RIO T-14 on his rod. I have cast his rod with all of these sink tips and I like it with all of them.
The T&T 1510 (whether 3- or 5-piece is a very nice, and very fine casting rod.
