It's about the fishing, not the casting. A few things:Would you be better off with a short head fishing the beach, with a long 14' rod OH casting. If you are new to OH 2hand rods, and are not good at casting yet
Bingo. The 40+ Beach Line is my favourite as well, though I don't consider it to be a long line relative to the 55'-65' distance lines out there. These distance lines were my frame of reference for the OP's 'long line'.My experience is somewhat limited, but I have spent quite a bit of time doing two handed overhead casting on the beaches and surf of Cape Cod. I find that the OBS sort of line works best with a single-handed rod and the standard OB, or the couple of equivalent lines out there, is best for the two-handed. The only time I changed that belief was when I had a high dune behind me, then having a shorter head helped. There's no reason a long-head (37' or so) can't be pulled just as far into the rod as a 30' head IF you're using an integrated line like the Outbounds, 40+ Beach Line (my favorite but now discontinued,) or the new Serum from Beulah. It takes just a bit more work to get the longer head back out for a re-cast, but after a bit of practice that's just not an issue, at least for me. I also chuck weighted Clousers, but I don't use a ton of weight on them either. If you need that much weight that could make a difference. With two-handed overcast casting there should be NO false casts, just a series (2 or maybe 3) of roll casts to get the line out of the rod guides and onto the surface. Everyone I've seen fishing two-handed on the Cape that was false casting ended up going nowhere. Four and five false casts and then putting the fly out 35' at most. It was almost comical and there were quite a few guys struggling with that. Roll cast, roll cast, backcast, forward cast. That's it. With the right setup 100' is easy.
Which is why 40' is about the longest I would go. Too much of a fiddle working the head out after stripping it all the way in. All of my heads for beach fishing are only 35' for this reason alone.Fishing for Stripers on the beach, the bass can be close , right in the wash. ???
What might they be?When 640 gr Scandi and 510 gr other type line performances are compared Scandi wins every time. 25% more line head weight has so big influence to performance than other type of taper can not compensate lighter weight.
But for fishing there are subjective issues which might make lighter line "better"
It's about the fishing, not the casting. A few things:
14' is too long (been there) so look at 11' to 12'.
fish hit close in so we want a line that we can strip in close and cast out there without loads of false casts - in other words a short line
we're chucking weighted clousers that need mass and turnover in our lines, which is not the strength of long lines
intermediate lines are the big fish producers and there aren't a lot of those available in long lines.
Short lines off the beach is where its at.
