For years my 10wt Horizon I was the love of my life. Great taper, tons of backbone and an amazing "damp" fee. Fished everything from 10 wt floaters to 600gr sinkers. I loved that rod... until it when over the gunnel.
Thought about replacing it off ebay but couldn't help but wonder how TnT had progressed over the years. Talked with Johnny Huff at Streams and Dreams (TnT prostaff/ R&D consultant, all around good guy) and ended up w/ a 10wt Apex built by Herb (who's a great combination of teacher, student and artist when it comes to building fly rods). Couldn't be happier with the rod. It's a good bit lighter than the Horizon it replaced but with that similar taper. The taper is fairly fast and has amazing reserves. That same reserve in the butt makes it the best fish fighting stick I've ever fished. And because it came from Highland beach, it's beautiful (black wraps w/ mint green metallic accents, Fuji Ti single foots, Wendell's Special cork grip...)
The Apex seems to have gotten lost in the shuffle during TnTs dark days. Never got press when it first launched and then seems to have been dropped during the rebirth. Fine by me so long as I have one.
As for the 8wt TNT... I believe they took the same 3M resin technology that every one else has (sage One, Loomis something, Orvis Helios...) and used it to make a Thomas Thomas fly rod Has all the same attributes that folks are praising in this thread but is blisteringly light, fast and beautiful thanks to Herb (blood red blank w/ matching wraps, metallic pink accents, Gucci Ti single foots, scaled down Wendell's Special... trust me, it's beautiful).
I've said it before; TnT rods are designed by folks that fish and are made by humans that care in western MA. You can tell. Don't even get me started on the service (I've got a thread around here some where about how awesome it is).
