The Hei$t is, in short, the ultimate benchmark ball. Decent length, with a smooth but deceptively strong backend reaction.
Compared to the Widow, I'd say less aggressive overall, which isn't a bad thing per se -- you can just stand a few boards further right anyways.
The Hei$t might be like an Ne10 but with less lope in the front of the lane (lower RG core). The cover gives it the length, while the core gives it its smooth, consistent roll.
Very, very, very highly recommended!
