Steelhead, the materials in your strings and cables are some of the best there is . I prefer 452X which is the same as the 450 except the 452X is just a smaller version. It just makes a nicer looking string is all and fuzzes a little less than the 450. I also use the Dynaflyte 97 and like it for strings. Now you could use 8125 which would gain you a little speed but not much. I make all my strings out of Dynaflyte and the cables out of 452X because the cables take more of a beating than the string does , especially on one cams. Now as Bgfisher said it still depends on who manufactured them as to if they are good strings and cables, because you can have the best materials, and you do, but if the manufacturing part isnt done right it wont make any difference in the quality of the string even with the good materials. 450 will have very little creep but when it does start to creep it is time for a new set.
