http://lane1bowling.com/tech/hook.htmlThe Hybrid dirty bomb and Dirty bomb both boast more back end potential, which to the break point makes it appear to have more total turn, and angle to the pocket
However, though the Super Carbide Bomb and Enriched both have more over all hook potential that the dirty bomb's, it is easy to get confused on the visualzation of back end movement, versus what is hard to see as a ball turns and sets up on the midlane... this too is considered to be part of the total hook.
So in conclusion, you have back end reaction vs total lane reaction.
Its up to the observer to decide what one is looking for.
