Double break ps4's and genetiks are great calls, but you might want to look at the warrior ritual pads also. The stock version is single break, but the pads are some of the most customizeable on the market, even more so than brian's. Depending on how you wear them and use them they will mold to that. If you use the top strap they will perform perfectly for your narrowfly, if you develop a wider flair somehow the pads can play as if they have a straight angle as well. They feel soft, but I promise you they will not shrink and hold their shape firm and strong. Another nice feature is you can wear them tight, loose, or whatever and they will all rotate very well.
Ultimately, if you're able try them on and see what you like best that will ultimately be the best avenue.
