I'm surprised no one has invited forum sponsor Thomas and Thomas to this party.
Their Horizons are extremely fast and sensitive with strength down low. I'm told the new Horizon II series is even faster, has the same backbone, but is lighter and easier to cast all day. I use T&T Horizons in 8- and 10-weights to fight constant wind where I fish and they're great. These guys are in Massachusetts; kinda makes sense they'd have some idea of how to build a rod for these waters, doncha think?
