I am no expert by anyone's standards but I have experimented with most different fletching styles. I make my own fletching from turkey feathers that my friends and I have taken. With that being said I own several different feather choppers.
I prefer 5' fletch simply because they provide a little more steering than the short fletching. Like mentioned above, short fletching will work fine as long as your bow is tuned well.
When it comes to noise, it seems to me that the more helical added creates far more noise than the style of fletching that is used.
Of course I prefer turkey feather fletching over any others. But there is a huge difference on feather life due to the quality of the feathers that a supplier uses. Like a lot of things in life, you get what you pay for. Good feathers just last way longer than cheap feathers.
Quality don't stop at the feathers, the Blitz is one fine fletcher that will last for ever. If I may suggest when you get a Blitz fletcher start with very little helical and you can add more if needed. When I first got my Blitz, I made some arrows with enough helical that they could double as flu flu arrows, and there were very loud, lol.
