Interesting thread. There is quite a "conversation" going on on "stripersonline" re two-handed(TH) rods for stripers.
Yuhine - your comment re short rod for wind and long rod for no wind is interesting.
I use rods from 11' to 12' - #7, 8, 9, 10. A few at 10'6" - # 6, 9 and 12.
I also have a 13'6" #11 that I never use.
All are built by me on CTS switch blanks - or beach blanks of my own design.
What do the longer rods bring to the table for you? I really do not see their application – maybe because I never do anchor-point casts. Just over-head.
Re the flys - this time of year in New England I would go with herring or large baitfish patterns. Kind of late for sand eels a I think.
Great to see your quiver for the stripers. I have heard a lot of good thing on those CTS blanks. But never got a chance to try their two handed.
I agree, long rods are not really necessary for the ocean fishing... the 16 footer on the beach is merely for the casting fun. Spey on longer line, or overhead casting on shooting heads. Particularly on the windy days, longer rods encounter more air resistance that I don't really enjoy hauling the big sticks around. 12-13 footers are doing just fine. But, during calmer days, longer rod with longer lines could be very useful in the stealthy fishing condition.
I fished a lot on a big river fishery before; big river is different story for the need of longer rod, a lot of currents and rocks so longer line control is needed.
below is video I made a couple years ago on this nice river fishery. fish are holding in some tricky currents, so sinktips, small flies and long cast could become essential elements to get into those fish. Mark
BTW, one of my favorite overhead casting rod on windy beaches - Guideline LeCie 13'7 8/9 light, powerful and sensitive (photo below)
