This set up will work, just fat strings will negate the benefit of the blue spacers. A popular set up is Kitty Regular and one red, one blue spacer in the 720s. The blue spacers make the gap wider for more sleep time for wrap and tangler tricks. Also starburst can be hard on strings, I consider Sochi to be a premium string and it cost more than bulk ploy which works just fine for looping practice. But like all things yoyo, set ups are subjective and if it works for you and you play more 2A, than go for it.
