The Deep Impact core design features very dynamic after-drilling numbers, which have proven very helpful for locking in your performance. In addition to strong core dynamics, we have wrapped it in our HK22C+ Hybrid cover, which gives it a strong mid-lane move and strong recovery. The Deep Impact has an RG of 2.480, a total Differential of 0.052, and an Intermediate Differential of 0.019. It features a 3 to 1 Differential ratio between the Intermediate and total Differential, which we have found yields the best continuation numbers. Our testers all reported a strong mid-lane move and lots of continuation, all of which is attributed to the addition of the HK22C+ Hybrid cover package. We have a strong asymmetrical ball that reads the mid-lane yet still maintains rotation, so it is very continuous.
