Well George, let's go shopping!
How long of a rod are you thinking? If on a headboat, then something around 7'-7'6" is nice. One a smaller private boat all that length can be awkward to use. if I were going factory-built, I'd go with a Black Hole Challenger Bank 701M, for headboat use.
The various and sundry factory-built Jigging World (now Tackle World) house rods - are all very nice pieces. Most, if not all are in the 7' - 7'6" range. I visit there a few times every year, just to keep up with their extensive new inventory additions. Always something new to see/purchase/obsess over at Tackle World.
For use from a private boat, there's all sorts of choices - my own preference is a custom CTS BS703 cut to 6'6" from the butt. Very, very nice for your app. You could even go for a BS702 cut the same way, if you are sticking to 6oz or less. I had Capt. Neil build me both, along with a BS704 (for true H/D togging - think Montauk, or fishing in the North Folk tide), as well as a BJ702 - which is also quite nice, and much more moderate in action. I can say that my BS703 is really special for up to 8 or so ounces.
My current togging obsession is a Jigging World Ghost Hunter 300gram slow pitch rod. But at only 5'8" and spiral wrapped too, this is a very unorthodox rod for blackfishing, and might not be to everybody's taste. Kills it for me though! WHAT a cool little rod!
BTW, if you like the Black Hole Challenger Bank blanks, but want to trim one from the butt to a slightly shorter length for a custom build, they are also available nekid from KilSong.
What I personally don't care for are the Rod Geeks XL rod blanks - too fast for my taste. But no denying that those blanks are VERY popular. So as in so many things - cars, sports teams, the woomens, your own tastes determine what you like.
