Back when I was a young fishing guide (1970's) most fly fisherman struggled to cast 50' honest feet, Scientific Anglers introduced the "Air Cell" lines and claimed they were 40% easier to cast because of their new much less friction........ Over the years they have improved the lines dozens of times , usually claiming 20/50% improvements to them. So in theory they are now around 400% better, so the same avg Joe should theoretically be able to cast this new lines easily 200' even if all their claims were halved......
Well in actual fact in my canoe after 50 years of taking folks out I have noticed that most fisherman still struggle to lay out 55/60 ft of line properly.
I can definitely draw a correlation to these flylines; to alot of these new products for Cubs, of course they are good and improved, and if you can afford $6000 shocks I think you should have them! But if you are convinced they will "save you" because of your inexperienced flying background......(bad theory). So in short if you are struggling to land in 300' with standard hydrosorb suspension, you probably will still struggle because of your inexperience.
Very few fisherman can cast 100/120 of fly line, Very few Cub pilots can land in no wind in 100/120'. Those two-factor will never change, regardless of the fly lines, or shocks they try.
It ain't the arrow, it's always been the Indian.......
