I am happy to see Estes re-release one of my favorite rockets of all time – The Sprint. The new release is a bigger meaner Sprint built on a BT 60 tube and using D and E motors and is a tribute to designer Mike Dorfler.
Last year I used a standard Sprint in several NAR contest and won each of them. The efficiency of the design incorporating the elliptical fins and a boat-tail is legendary.

I have a Sprint clone that I use as a demo rocket at Cub Scout launches. Even on an A8-3, it’s noticeably quicker off the pad than your garden-variety 3FNC like the Alpha.
