I've tried nothing modern but I used Masterline Chancellor Chalkstream fly lines back in the day and they had a bumpy texture. I remember they were much better at shooting than the 444's I used previously if that's a fair comparison.
I also currently use real silk lines on my bamboo rods that really zing so in my experience texture augments the ability to shoot line more easily.
BTW - The noise doesn't bother me, heck I like reels that click...
I don't know about most folks but because I am most often fishing someplace where I don't have a lot of backcast room, I shoot line on almost every cast I make so a textured or a clean smooth line makes a difference to me.
OT but related, when the Cortland Sylk first came out, it had a "stickiness" problem. I tried one and quickly got rid of it because that stickiness was most noticeable when I tried to shoot some line...
Bottom line, even though the OP is talking about a 2wt line and one would assume that means no 40 foot line shoots; it's a big help to more easily shoot even a few feet of line, especially when casts are short with not much line belly involved.
